TT#124275 Add 'Login to CSC' button in subscriber page

* upon pressing the button, a new session object
	    with selected subscriber's details will be inserted
	    in Redis, and also a new ngcp-panel_subscriber
	    cookie will be created containing the session id
	    of the previously created session object; then
	    the user will be redirected to CSC v1 address
	    where the selected subscriber will be authenticated
	    based on the cookie and Redis info
	  * the new button will be available for admin,
	    reseller, ccare and ccareadmin roles
