Remove the deprecated verify-tempest-config CLI

Tempest CLI verify-tempest-config was deprecated
4 years ago.

With assumption of all the users of this CLI have
moved to new CLI 'tempest verify_config', it is
time to remove the old deprecated CLI now.
'verify_tempest_config' should be now used as
'tempest verify_config'

The following commit gives the idea of deprecation
