* Makes the mysql role a dependency of edxlocal
* Moves memcached install into new role
* Installs memcached if EDXAPP_MEMCACHE contains localhost

This avoids a class of confusing problems where a user might be given
access to two DBs and then when starting the app, fail because they can
only access one DB.

edxlocal is too generic and does a lot of things.  This is the beginning
of separating it into roles that are more single purpose and easier to
understand.

- Fixed issue with migration user not having access to analytics databases
- Further consolidated creation of analytics databases and users

ECOM-2180

Consolidated database and user creation tasks, eliminating duplicated code.

ECOM-2180

Granted the local ecommerce database user full privileges. This will ensure developers can continue to run migrations without any special commands or environment variables.

ECOM-2185

Make sure the local databases get created for the ecommerce app
and update some other databases that should be wired back to the
settings in their corresponding roles.

Always write the supervisor files and link them as necessary.

Drop the configs in the supervisor available directory. Instead of having a
seperate cfg dir for each service.

Seperate devstack logic from disabling supervisor tasks. Add the new flag so
devstack continues to not startup supervisor. Use new supervisor_available_dir
everywhere.

Remove mongo logic from abbey and remove stage_release. This should completely
remove our tie ins to mongo.

Also removing monitor repos script which depended on stage_release. We can add
in similar logic when we're ready to automate building the AMIs on rc branch
creation.

Updated requirements.
