Add cli functional tests from tempest

test_readonly_ceilometer is migrated from
./tempest/cli/simple_read_only/telemetry

A new 'functional' target is available in tox. In order for these
tests to pass OS_PASSWORD, OS_AUTH_URL, OS_USERNAME
and OS_TENANT_NAME need to be set in the environment before running
the tests, e.g:

    source src/devstack/openrc demo demo && tox -efunctional

Subsequent patches will remove tests from tempest and add thes tests
to project-config for gate checks.
