Module novaclient.v1_1 is used as implementation of V1.1, V2 and V3.
Since future development(microversioning) will be done across V2,
implementation should be done in appropriate module(to prevent misleading).
Despite the fact that implementation for all versions are equal, discover
method for contrib path worked only for v1.1. This patch fixes this bug and
modifies shell tests to check all versions.

To remove aliases for `arg` and `env` functions in novaclient.utils,
we should use `arg` and `env` directly from cliutils in novaclients modules.
This patch removes aliases in `novaclient.utils` and starts using
`args` and `env` from novaclient.openstack.common.cliutils directly.

Bug 1195670
Nova supports force_delete or restore instance in the API level,
thus it makes sense to support this feature in novaclient.
