No option to pass different profiles

[JBarnes94]

There is no option to pass profiles as defined in .aws/

This addition would make it easier to use in a multi account environment.

Profile name and environment can be passed (with default value to keep existing functionality)

Then a session can be created with the profile information,
and the client from this session.
