Configuration at module level is broken

[rvalle]

cloudstack modules can be configured via 3 diferent ways

• environment variables
• cloudstack ini files
• module supplied parameters

If environment parameters are not supplied ini search path will kick in. A SystemExit exception is raised if no ini file is supplied.

The code responsible for reading configuration from modules is unreachable if no ini file is present.

Therefore using a cloudstack ansible module configured only via module parameters does not work and the following exception is raised instead:

'''
Config file not found. Tried /home/ansible/.cloudstack.ini, /ansible/cloudstack.ini
'''

or similar.
