New variable required to generate ZTP configuration.
Note that we can only pass strings with extra_vars in AWX API (no list
or dict).

JIRA INFRA-458 #action In Progress

Using flask-login request_loader, we can validate jwt tokens.
This allows to use the same decorators for the web UI (using cookies)
and the API (using JWT) as well as the current_user local proxy.

JIRA INFRA-414

Use the before_flush hook to trigger the core services update.
It's much nicer than having to call a method in several places.

The core services update is triggered on creation/modification/deletion
of an Interface.

In the before_flush we can manipulate the session (add objects) but we
shouldn't call commit.
The db.session.commit() was removed from the launch_task method.

Avoid calling the database several times.
Several attributes can be updated in one call.

Only save exceptions that occur before the AWX job was triggered.
If the AWX job failed, we can refer to the logs on AWX.

JIRA INFRA-403

Both AWX_VM_CREATION_ENABLED and AWX_JOB_ENABLED shall be set to True
to enable VM creation.
An extra variable is used because the core services can be updated from
csentry-test but VM creation shouldn't (for now)

Allow to create a VM or Virtual IOC

AWX jobs should only be triggered on the production server (not from
staging). At least until we get a full staging environment.
