Prepare Watcher to use openstacksdk. This patch introduces a new function in the clients module to create a openstacksdk connection either using a user token, an existing keystone session or a new keystone session. Additionally, it adds a method to the newly introduced wrapper classes to create nova server, hypervisors, flavors, etc from the objects returned by the openstacksdk compute proxy. This patch also deprecates the nova_client configuration options and adds keystoneauth configuration options into the nova conf group, since that is required by the openstacksdk to create a Connection. The nova group will be the preferred section to configure the connnection to nova, with the currently used watcher_clients_auth as fallback to avoid upgrade impact. In the future, once all services are accessed through the openstacksdk, the watcher_clients_auth section should be removed. Add a call to the configure_keystoneauth function in the the devstack plugin to populate the [nova] section with the keystoneauth parameters.
