Check configuration file permissions in CI

Typically, non-executable files should have 660 or 600 and executable
files and directories should have 770. All should be owned by the
'config_owner_user' and 'config_owner_group' variables.

This change adds a script to check the owner and permissions of config
files under /etc/kolla, and runs it at the end of CI jobs.
