Add support for OpenShift/OKD 4.x

oc logs -f pod/chi-dev-dev-0-0-0
Necessary directory '/var/lib/clickhouse/' isn't owned by user with id '1000740000'

This problem is caused by boilerplate code inside Docker image itself, but let's keep this ticket here to track the entire progress on adding support for OpenShift.

Also, it does not appear in the console of openshift, when searching the operatorhub. Has it been discontinued?

kubectl get packagemanifests  -n openshift-marketplace |grep -i click

kubectl get catsrc --all-namespaces
NAMESPACE               NAME                  DISPLAY               TYPE   PUBLISHER   AGE

Hi @davidkarlsen , no it is not discontinued, we update it regularly: https://operatorhub.io/operator/clickhouse

Something else is required in order it or be listed on openshift-marketplace. Will look into that.

@alex-zaitsev that sounds good. Look at the catalogsources I listed - should it be available from them - which included community-operators - or could it be because the operator does not match cluster requirements (k8s version etc)

@alex-zaitsev was the OCP support fixed?
