feat(EnPRO): extend OTel-shop with MongoDB, add Ansible, Terraform an…

…d EDMM models (#9)

* [productcatalogservice] Added MongoDB

This adds a MongoDB to the demo instead of parsing the JSON before usage. The implementation is not yet perfect but it works for now. Thus far, only docker compose is supported.

Things that still need more work are:
- The Go application still uses static MongoDB username and password and the hostname and port are also static. This should be changed to use environmental variables instead.
- I wasn't able to check whether the healthcheck of the MongoDB works or not.
- Is the resource limit too generous?
- Should we fix the port inside the MongoDB container to its default value (i.e. change using a secret here to 27017)?

* [productcatalogservice] Changed to use env vars

This changes the productcatalogservice to use environmental variables for the MongoDB username, password, hostname and port.

* [K8s] Added MongoDB

*Disclaimer:* this is not working yet!

* build(deps): bump docker/build-push-action from 6.0.1 to 6.1.0 (open-telemetry#1620)

Bumps [docker/build-push-action](https://github.com/docker/build-push-action) from 6.0.1 to 6.1.0.

## Welcome to the OpenTelemetry Astronomy Shop Demo
## Welcome to the OpenTelemetry Astronomy Shop Demo with DeMAF extension

This repository contains the OpenTelemetry Astronomy Shop, a microservice-based
distributed system intended to illustrate the implementation of OpenTelemetry in
a near real-world environment.

Our goals are threefold:
FOR THE ORIGINAL README [CLICK HERE](./README_original.md).

The purpose of this fork is to extend the Astronomy Shop in three ways:

- Add a database to showcase that a persistence layer can also be part of the architecture without causing any problems.
- Create a deployment model to deploy the shop using [Ansible](https://docs.ansible.com/) and [Terraform](https://developer.hashicorp.com/terraform/docs) besides the given [Docker-Compose](https://opentelemetry.io/docs/demo/docker_deployment/) and [Kubernetes](https://opentelemetry.io/docs/demo/kubernetes_deployment/).
- Add translated EDMM models for [Kubernetes](./edmm/otel-store_k8s_translated.yaml), [Ansible](./edmm/otel-store_ansible_translated.yaml) and [Terraform](./edmm/otel-store_terraform_translated.yaml) to showcase the transformation result of those three DeMAF plugins in [EDMM](https://github.com/UST-EDMM).


### Database Integration
The database integration ensures that also a persistence layer is used in the provided demo-application,
making the architecture more comprehensive.

Therefore, a [MongoDB](http://mongodb.com) is added, which adds the products of the shop into the database as JSON entries.
In the default variant of the astronomy shop, only a plain file is used to provide the products.

Thus, the logic of the `productcatalogservice` is adapted, to initialize and use the additionally provided MongoDB.

The changes of the `productcatalogservice` and the addition of the MongoDB is integrated into all deployment variants in this fork.

### Translation to Ansible

To verify the [Ansible MPS Plugin](https://github.com/UST-DeMAF/ansible-mps-plugin) the Astronomy Shop is available as Ansible installation.
It is based on the [Docker-Compose](https://opentelemetry.io/docs/demo/docker_deployment/) and installs all components of the shop as docker containers on the local Docker runtime.
For each component there is a dedicated Ansible Role representing the loose coupling of the components.

A usage guide can be found in the dedicated [README in /ansible](./ansible/README.md).

### Translation to Terraform

To verify the [Terraform MPS Plugin](https://github.com/UST-DeMAF/terraform-mps-plugin) the Astronomy Shop is available as Terraform installation.
It is based on the [Docker-Compose](https://opentelemetry.io/docs/demo/docker_deployment/) and installs all components of the shop as docker containers on the local Docker runtime.

A usage guide can be found in the dedicated [README in /terraform](./terraform/README.md).

### EDMM Models

For all three evaluated technologies (Ansible, Terraform, Kubernetes) there is a transformed target model available.

The target EDMM models can be found in the [/edmm directory](./edmm)

In each model the goal is to retrieve a component for each deployed Astronomy Shop component
and as many _connects-to_ and _hosted_on_ relations as possible.

This in common, there are also differences in the target models.

Due to the imperative character of Ansible, in the [Ansible target model](./edmm/otel-store_ansible_translated.yaml), each component has operations representing the installation of the Docker containers.

- Provide a realistic example of a distributed system that can be used to
demonstrate OpenTelemetry instrumentation and observability.
- Build a base for vendors, tooling authors, and others to extend and
demonstrate their OpenTelemetry integrations.
- Create a living example for OpenTelemetry contributors to use for testing new
versions of the API, SDK, and other components or enhancements.
In the [Terraform target model](./edmm/otel-store_terraform_translated.yaml), there are common component types for all _docker_containers_,
as they all use the same terraform ressource type. This is different in the other two evaluated technologies, where each component has a dedicated type.

We've already made [huge
progress](https://github.com/open-telemetry/opentelemetry-demo/blob/main/CHANGELOG.md),
and development is ongoing. We hope to represent the full feature set of
OpenTelemetry across its languages in the future.

If you'd like to help (**which we would love**), check out our [contributing
guidance](./CONTRIBUTING.md).

If you'd like to extend this demo or maintain a fork of it, read our
[fork guidance](https://opentelemetry.io/docs/demo/forking/).

## Quick start

You can be up and running with the demo in a few minutes. Check out the docs for
your preferred deployment method:

- [Docker](https://opentelemetry.io/docs/demo/docker_deployment/)
- [Kubernetes](https://opentelemetry.io/docs/demo/kubernetes_deployment/)

## Documentation

For detailed documentation, see [Demo Documentation][docs]. If you're curious
about a specific feature, the [docs landing page][docs] can point you in the
right direction.

## Demos featuring the Astronomy Shop

We welcome any vendor to fork the project to demonstrate their services and
adding a link below. The community is committed to maintaining the project and
keeping it up to date for you.

For the Kubernetes model there are two variants. The [first](./edmm/otel-store_k8s_translated.yaml) is the actual result of the translation, lacking _hosted_on_ relations.
That is, as the Kubernetes plugin only creates _hosted_on_ relations when a component named _container_runtime_ with a matching type is present in the TADM.
Therefore, there is a [second target model](./edmm/otel-store_k8s_translated_with_container_runtime.yaml) where this _container_runtime_ has been manually added, before creating the relations.
Thus, all components obtain a _hosted_on_ relation.
