[resources] Cannot set resources for initContainers

[nttvgonzafe]

Currently the spec doesn't allow setting the resources field on initContainers. On clusters that enforce setting resources for all containers, this blocks databases created by the operator from starting.

A possible workaround is to add a LimitRange with the default resources. Anyway, this initContainerResources can be a good thing to have.

Hey @nttvgonzafe, thanks for opening this issue! Ideally, how would you envision this working? Would it be exposing a top-level field on the cluster CRD for example?

Hey! I think so, exposing a initResources at the same level as resources in the CRD with the same schema should be intuitive. Edit: initResources or initContainerResources whichever seems more idiomatic.
