Support for Tolerations

Summary

Request to add the support of tolerations as we're looking to scale down the PB padawan nodes and move mattermost to a specific node pool.

Steps to reproduce

Current chart doesn't support tolerations.

What is the current behavior?

We can't assign a pod to a specific node pool/workload.

What is the expected behavior?

Able to schedule the mattermost pod on a node with tolerated taint.

Relevant logs and/or screenshots

N/A

Possible fixes

Update the mattermost.yaml template to support tolerations.

Spoke to @michaelmcleroy and said this could be done.

AC:

• Add templating to allow this chart to support taints+tolerations via the mattermost custom resource
• Bump version in chart/Chart.yaml and CHANGELOG.md
• Re-generate README
• Create Merge Request into BigBang with new package tag that includes above additions
•

Tried adding the toleration under scheduling as described in this post, but it didn't work.

Mark mentioned a similar problem on his ticket here.

Note: I did not see the error Mark mentioned. Instead my Mattermost pod was just being blocked by the taint.

Toleration code is working. Just needed to pass the toleration values for mattermost-operator, so mattermost could launch.

Left small comments on the MR:

• versioning needs to be fixed since this is a BB owned/built helm chart (on these we do a standard semver update and then always append -bb.0 rather than bumping the bb version.
• one of the readme values needs manual intervention to escape a character
