Rethink the get() methods required parameters

[Temikus]

Ideally even for zonal and regional resources get() method should try to find the resource enumerating across all zones and regions and not require any parameters.

This seems to have been the case but changed when migrating to 1.0, judging by the test changes:

• 401b13c
• edd746f
• be33cd8

What I think needs to be done is to make zone/region parameters optional in get() and if none are provided, look up the resources ourselves.

@icco WDYT?

Sorry, nevermind, already filed under #352
I'll close this out and get some info there.
