fixed and reintroduced syncronize test, fakerunner object needed become_method to be it's default 'sudo'

Nothing we can do, when it sanitizes ssh_urls it's simply overzealous.

Was using persist_files=True when specifying the create paramater,
which breaks pipelining. Switched to use delete_remote_tmp=False instead,
which is the proper way to preserve the remove tmp dir when running
other modules from the action plugin.

overwrite and not merge hashing
corrected merge vs combined in all pertinent sections
fixed typoe in combined_Vars
removed redundant inventory call, moved grousp to proper priority
readded inventory vars to runner's vars

Make the example somewhat more feature complete

New users might think that "state=started" implies that the service is also started at boot-time, which isn't.
By adding it, this change makes a clear distinction between the service state, and whether it is enabled (at boot).
And makes the example more feature-complete as this is what most people would be doing anyway.

Document Environment in tasks as well
