Do not use env var conf defaults

Falling back to environment variable credentials is convenient for
development but could lead to unexpected credentials being used during
tests. Also this is not a known practice for tempest tests.

This change removes the env var defaults and explicitly sets the
credentials to use in prepare_test_env.sh.

Pre and post grenade tests also get their config from the conf file
rather than the environment.
