Add Dockerfile and docker-compose.yml

[bensig]

This is a simple way to add docker support using a small docker image (ubuntu/latest) and installing the latest ord release using install.sh instead of building from source which uses a much bigger image.

Paths in docker-compose.yml can be updated to run on OS X, or in a custom path instead of /ordinals - for example if you prefer /var/local/ord or the more bitcoiny ~/.ord.

Can be easily run with:

docker-compose up -d

Updated docker-compose.yml to include default paths for ord index data in each OS

install.sh doesn't seem to work properly inside a docker image. Maybe we should build from source?

I'm on a Mac and getting this:

 [7/7] RUN ./install.sh --to /ordinals:
#10 0.643 install.sh: Could not determine target from output of `uname -m`-`uname -s`, please use `--target`: aarch64-Linux

I want to wait until we have a minimal dockerfile, that people find useful, before starting to dive into docker compose, and adding more features.

We created a PR with a minimal Dockerfile, which still has issues: #2786

That minimum Dockerfile has a huge image for building rust. This Dockerfile uses a smaller image which was chosen based on the comments there. @raphjaph I fixed the Dockerfile so that install.sh works correctly now.

There are a couple issues:

• ubuntu-latest is a large base image that isn't necessary for running ord. I'd like to use a minimal image for actually running ord.
• We want to build from source, not install a prebuilt binary, so the builder does need to include the necessary tools to build ord.
