operator: changes to support multiple api versions

By moving the core deployment API fields that are expected to be
supported by all future API versions, we could minimize the code
duplication. Hence moved such fields into the `base` package that
supposed to inherited by all the API versions.

Made '{Controller,Node}Resources' specific to v1alpha1 api as upcoming
v1beta1 version plans to deprecate them in favour of container specific
resources.
