Fixes #6154, #6253 - ak/ch name resolver for lfenv

Fixes a few issues with activation-key and content-host

1) This provides resource_alias from --environment, --environment-id
to --lifecycle-environment, --lifecycle-environment-id

2) fixes issue with resolving the environment by name:
--environment or --lifecycle-environment flag did not work
resolving by name was using environment resource instead
of the lifecycle-environment resource.
