Remove runAs and fsGroup to be compatible with OpenShift
Closes #139 (closed).
With this change agentk is not using the nonroot user on OpenShift and works fine:
On kind:
$ k exec gitlab-agent-7f4cb86b7f-lhpqs -- sh -c 'id'
uid=65532(nonroot) gid=65532(nonroot)
On OpenShift:
$ k exec pod/gitlab-agent-864fcf9c97-6dkzc -- sh -c 'id'
uid=1000630000(1000630000) gid=0(root) groups=1000630000
Updating kas is out of scope here as that needs to be consistent with whatever we'll do for other containers i.e. it's part of gitlab-org/charts/gitlab#1069. Moreover, that would mean Chart changes - kas deployment is currently consistent with other deployments and I'd like it to stay that way. No point in fixing it if everything else doesn't work (?) anyway.
