Copy functional tests from tempest CLI

The tests have been copied almost as they are from tempest repository,
location: tempest/cli/simple_read_only/data_processing/
master commit: 6e8e5e1f882ec339fe3838e3e52345d2e1c5f5a1.

Changes made:
 - remove dependency to global CONFIG object; test_sahara_plugins_show
   now dynamically gets the list of available plugins instead of relying
   on the configuration;
 - remove test.attr and test.idempotent_id decorators, not available
   in tempest-lib (for now?)

Changes heavily adapted from the corresponding novaclient and
ceilometerclient commits.
This is part of the effort of moving CLI tests to project repositories.
