add file for identity v1 and associated spec (need it to capture swath method);
intermediate update
(Pairing with Chris Johnson)

Fixed accidential circumvention of Service#new.  Prevously was not
calling setup_requirements so the requests and models were never
being loaded.

Also corrected the model module scoping.
latest updates to handle consolidation of Identity::V2 to IdentityV2, etc.
nuke old stuff for v1 Identity provider - will complete later
correct token spec
correct tenants spec
restore retry logic
roles spec
credentials specs
clean up puts
model specs
rebuild all VCR cassettes
tweak approach to params per Kyle - good action
refactor to handle admin vs non-admin requests - much better thanks to @krames.
use params hash for params - missed these
cruft
move to common module in preparation for moving up to fog-core
make sure these ivars are set when there is no unscoped token in play
change to "call" as this will likely be the only public method
