- persistent_state represents whether a profile is stored on disk
- persistent_state defaults to 'present'
- When there is no type specified for the profile, it is enough for a
profile with the same name to be stored on the target's systems file
system. Otherwise the role will fail
- state now represents the runtime state and can be up, down or
unspecified
- translate the state definitions into actions that will be performed.
The actions correspond to the previous states.
- add the possibility to write unit tests to only verify parts of the
resulting connection dictionary to only check for the expected changes
instead of the full connection that can also contain unrelated defaults
