[Feature Request] Support for OpenShift

[hishamanver]

Is your feature request related to a problem? Please describe.

I attempted to deploy temporal via helm into an OpenShift cluster

Ran into issues running the temporal server and temporal ui containers on openshift due to security constraints (running on openshift - https://cloud.redhat.com/blog/a-guide-to-openshift-and-uids)

Identified the root cause to be the following sections:

• server issue Temporal Helm Charts: Acknowledging Banzai Cloud #1 - https://github.com/temporalio/helm-charts/blob/main/charts/temporal/values.yaml#L83-L85
• server issue helm chart: updating images/tags w the release (0.20.0) #2 - added to issue: [Feature Request] Support for OpenShift docker-builds#241
• ui - added to issue: [Feature Request] Support for OpenShift ui#2327

Essentially what we are observing is this helm chart enforces specific UID and GID for the running containers that do not match the predefined ranges in OpenShift and therefore fail with the following error:

# kubectl get events

Describe the solution you'd like

Helm chart should not enforce a default uid or gid, users should inject these values if required

To get around this issue the following values file was used and confirmed to work

temporal:
  server:
    securityContext:
      fsGroup:
      runAsUser:

Essentially I am unsetting the predefined values
