Subject: [PATCH 1/2] Refactor: libstonithd: functionize fudging metadata of
 RHCS-style agent to make specific parameter non-required

The parameter `port` of RHCS-style fence-agents is fudged to be shown as
`required="0"` in the metadata output by `stonith_admin --metadata` or
`crm_resource --show-metadata`. So that users know they don't have to
configure it. Pacemaker handles and passes the parameter to the agent
when executing it.
