We are starting using a git branching model like the Elastic Stack projects. 

This commit makes sure this `7.7` branch is using the 7.7.x-SNAPSHOT Docker images and  this branch will be used for the development and release processes  for the Helm Charts 7.7.x
The cluster names created for running tests can't contain the `.`
character which is part of the branch name.
For doing the integration tests some GKE clusters are created. There is
a dedicated job to cleanup these clusters at the end of the tests.
This commit fixes the Jenkins configuration to make sure this upstream
job (which does not need parameter) is triggered.
This commit updates the remaining links to GitHub and Jenkins which
had `master` as the branch name to 7.7
[helm] bump helm version to 2.16.6
* [script] Update bumper script to handle SNAPSHOT versions

This commit updates the `bumper.py` script to handle the
workflows for updating the versions to test staging artifacts
and before a release, for example:

- update 7.7.0-SNAPSHOT to 7.7.0 before tagging a release, by running
  `env BUMPER_VERSION_7="7.7.0" ./helpers/bumper.py`
- update 7.7.0-SNAPHSHOT to 7.7.0-abcdefgh for testing staging artifacts
by running:
  `env BUMPER_VERSION_7="7.7.0-abcdefgh" BUMPER_USE_STAGING_IMAGES="true" ./helpers/bumper.py`

For now this script do not handle the bump from 7.7.0 to 7.7.1-SNAPSHOT
for the next developement iteration after a release. In the meantime
this update should be done manually.
…c#582)

The multijob configuration for testing staging 7.7 artifacts was
referencing jobs from another branch. This commit makes sure the
configured jobs are all from the same git branch.

This commit initiates the 6.8 branch which will be dedicated to the 7.x.x releases for the Helm Charts. It will allow to:

- test this branch with the daily Stack Docker images 7.8.0-SNAPSHOT via dedicated Jenkins jobs
- test the staging 7.8.x Docker images before a release

This branch is based on https://github.com/elastic/helm-charts/tree/7.7/ which was initiated in elastic#541.

Also related to elastic#602.

Kubernetes doesn't accept `_` characters in resources names.
This commit fix the secrets names in the examples we provide by
replacing `_` by `-`which Kubernetes is accepting.

Source: helm/helm#6477
This PR disable nss dentry cache for Elasticsearch and Kibana
readinessProbe.

On affected system (nss < 3.52), the curl commands used by
readinessProbe are filling dentry cache which is observed in some
cases to be never reclaimed.

Elasticsearch and Kibana Docker images are based on CentOS 7 which
is using nss-3.44.0-7.el7_7.x86_64 and are affected by this bug.

This PR disable nss dentry cache in readinessProbe as a
workaround.
* [metricbeat] support deployment/daemonset specific metrics
* chore: rename test_adding_legacy_labels to test_adding_deprecated_labels
Co-authored-by: Julien Mailleret <8582351+jmlrt@users.noreply.github.com>
This commit fix an issue introduced in 8ed75a9 where helm
install/upgrade is failing if a NodePort service is defined (see [0] for
more details).

Logstash headless service used to manage Statefulset does not anymore include
`.Values.service.ports` and include only Logstash httpPort.

This is done because headless service `ports` doesn't accept `nodePort`
values that can be included in `.Values.service.ports` when adding a
NodePort service.

…c#882)

This commit update metricbeat chart dependencies to get
kube-state-metrics subchart from the newly relocated stable repo url
(https://charts.helm.sh/stable).

This is required because the legacy stable repo url will not work
anymore starting November 13th.

This commit updates Kubernetes [rbac.authorization.k8s.io][0] api from
v1beta1 in apm-server, filebeat and metricbeat charts.

- `rbac.authorization.k8s.io/v1` has been released in Kubernetes 1.8
- `rbac.authorization.k8s.io/v1beta1` is being deprecated in Kubernetes
1.17 and will be fully removed in 1.22

In addition, this is required for Helm 3 support to make
`helm lint --strict` happy.
