Vincent Françoise 2966b93777 Add strategy_id & goal_id fields in audit template
In this changeset, I updated the 'goal_id' field into the AuditTemplate
to now become a mandatory foreign key towards the Goal model. I also
added the 'strategy_id' field into the AuditTemplate model to be an
optional foreign key onto the Strategy model.

This changeset also includes an update of the /audit_template
Watcher API endpoint to reflect the previous changes.

As this changeset changes the API, this should be merged alongside the
related changeset from python-watcherclient.

Partially Implements: blueprint get-goal-from-strategy
