Michael McCune ef3815988e rename service api modules
This change renames the service api modules to be organized under the
sahara.service.api package. A v2 package has been added which holds the
equivalent v10 and v11 functions. To make the api version setup
transparent to the caller, the global OPS variable has been refactored
into the base sahara.service.api package.

Changes
* create sahara/service/api package
* rename sahara/service/api.py to sahara/service/api/v10.py
* rename sahara/service/edp/api.py to sahara/service/api/v11.py
* correct occurances of old imports in code and tests
* rename sahara/tests/unit/service/test_api.py to
  sahara/tests/unit/service/api/test_v10.py
* add initial v2 equivalents for current api services
* move global OPS object into the sahara.service.api package
* add documentation for the api service layer
