fix(apache#4948): Move handling of IntegrationPlatform CR to a separa…

…te operator.

Add a separate platformcontroller subcommand to kamel, amend install command and other installations (OLM, kustomize, helm) as needed.
The platformcontroller works as the operator command but runs an operator that handles just the IntegrationPlatform crd;
the operator dose not manage IntegrationPlatform crd any more.
