Remove last dependency from keystone client
EC2 tests use keystone client to generate AWS style credentials if they
are not configured (like in the gate).
Implementing the identity v2 functions to list and create AWS style
credentials in tempest's identity_client.
Replacing calls to keystoneclient with calls to identity client.
The generation of AWS credentials is moved one level up to the
client manager, because the boto client would otherwise depend
on the identity client. Client manager already has an identity
client and can prepare credentials for the boto client if needed.
