Add new parameter in place of deprecated one

The allow_tenant_isolation parameter has been replaced by
use_dynamic_credentials. As such added the parameter and removed
the old one. The default location from where tempest expects
to pick up the file containing credentials is also added
in the patch. The file location is only added when the file
is being used.
