Added basic changes for aix user provider
Fixed group tests for aix to use short group/user name
aix: enable user tests, username by default are shorter on aix
aix: aix uses different password shadow file.
aix: useradd doesnt support -r like other unix, so sytem account is created by adding to "system" group.
Use valid short name for group members
aix: use password hashes, aix style from /etc/security/passwd
aix: -m option option to usermod errors on aix
universal_options in useradd provider is an array.
