This patch added the code of specific RSD plugin in OSC, which allow
user to issue node composition command through OSC, like
'openstack rsd compose
--rsd-url "https://localhost:8442/redfish/v1/"
--rsd-username "admin"
--rsd-password "admin"
--rsd-disable-verify
--name "Fake-Name" '
Note: for node composition command, it only support "name" parameter
now. More functionalities will be implemented later.
