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.
