* Disable helm CRD installation for disable-helm-controller
The NewContext package requires config as input which would
require all third-party callers to update when the new go module
is published.
This change only affects the behaviour of installation of helm
CRDs. Existing helm crds installed in a cluster would not be removed
when disable-helm-controller flag is set on the server.
Addresses #8701
* address review comments
* remove redundant check
