Do not fail immediately if wakeup fails, retry instead

Since we restart keystone immediately and then do a wakeup call,
sometimes the wakeup call fails because it cannot connect to the server
yet.

To avoid that, we should just retry the wakeup.

Fix setting of users default tenant

Keystone v2.0 api expects tenantId to define the default
tenant, not tenant_id (which is the EC2 credential tenant)

Otherwise the property is missing in the created
user, which causes compatibility issues later (for example
bnc#859463)
Use provider for setting token format

The other setting triggers a deprecation warning.
