Fix test_encryption_vol_type to take admin creds from conf

Heat integration test test_encryption_vol_type will not work in environments
where admin user is named differently or does not have the same password as
that of the demo user.

The admin credentials is now made available via heat_integrationtests.conf.
The tests which require admin privileges should be run only if admin
credentials are available and use the same.
