User Story:

Some background on the Licenses field:

https://github.com/openshift/installer/pull/3808#issuecomment-663153787

https://github.com/openshift/installer/pull/4696

So we do not want to allow licenses to be specified (it's up to customers to create a custom image with licenses embedded and supply that to the Installer) when pre-built images are specified (current behaviour). Since we don't need to specify licenses for RHCOs images anymore, the Licenses field is useless and should be deprecated.

Acceptance Criteria:

Description of criteria:

• License field deprecated
• Any dev docs mentioning Licenses is updated.
