Undercloud Validations - Deprecated (replaced/removed) opts
Undercloud Validations - Deprecated (replaced/removed) opts

Add a validation method to check for invalid (replaced/removed)
configuration options. Fail the validations if any such options
are detected in the configuration.

After the deprecation period is over and options are removed we
can add options to 'invalid_opts' to make sure users update
their configuration.
