Sometimes we get an instance id back from the creation call but then
get an exception saying the ID was not found when we do a get_all_instances.

Set params on BlockDeviceType instead of BlockDeviceMapping.

Use SSD backed EBS instead of standard.
Delete the volume upon abbey termination.

At 30 minutes we still hit it sometimes when building from a bare ubuntu box.

Defaulting it to hammer for now.

The instance gets tagged with the repo and hash that was deployed.

Instead, we take any extra_vars that have a suffix of '_version' and
make sure those exist as tags on the AMI. All other vars do not get
saved anywhere.

Turn on instance tagging with abbey.

Also use the proper return code when abbey has issues.

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.
