- auth_system
- region_name
- service_type
These are config settings that could be left out in many scenarios, but
the current code is requiring them. In particular, "service_type" is a
new one in PR #7444 so if we add that and don't set a default, then
existing .ini files won't work:
```
File
"/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ConfigParser.py",
line 618, in get
raise NoOptionError(option, section)
ConfigParser.NoOptionError: No option 'service_type' in section:
'openstack'
```
The existing description does not make 2 things clear.
1) This is an environment variable
2) It must be set on the _controlling_ host, not the remote host.
If the repo_path contained multiple '.git' strings, the _git_repo_info()
call resulted in a traceback. This change removes the trailing '.git'
and resolves the traceback.
Output a useful message if `git submodule update --init --recursive` not
yet performed
```

Also improved handling of detached HEAD when printing out version
information.
