Make namespace creation as optional

[sumeet-zuora]

Can we make the creation of namespace as optional at https://github.com/percona/percona-helm-charts/blob/main/charts/psmdb-operator/templates/namespace.yaml as we might already have namespace created from different automation

Hello @sumeet-zuora ,

yeah, we have it in our plans and it might be delivered under https://perconadev.atlassian.net/browse/K8SPSMDB-930

Can this be also added to pxc, pg and ps operator seems all have same issue

@sumeet-zuora From what I see pxc is affected and I will create a PR for it, ps and pg don't seem to be affected since they don't create namespaces (but correct me if I'm wrong and don't see something).

In ps the watch namespace is only for where it is deployed, pg watch namespace have proper variable.

Role and rolebindings have mentioned the watch namespace, but values.yaml don't have it defined.

In both, it is expected as string or single namespace. Where as I think in psmdb it is multiple namespaces separated by comma.
