* Massive restructure of actions folders
** This was followed by a series of renames and changes
that were requried throughout the codebase.
* The 'tenant_setup' app is gone and merged into the core
actions app properly.
* Action classes and tests now split into multiple modules.
* Clean up of test decorators so they are only set at the
class level rather than per test (much cleaner).
* Actions now allow version structuring in some capacity
similar to the api modules.
* Added app configs for 'stacktask.action.v1' and
'stacktask.api.v1' to avoid a duplicate label problem
in django.
* Moved the startup checks to their own app, and ensured
that it is imported last. This is required because
'stacktask.api' was being imported before
'stacktasl.actions.v1' and thus not all the action classes
had been setup yet. This way it is a global set of checks
that always occur last.
