 This is a Dummy Resource Agent. It does absolutely nothing except
 keep track of whether its running or not.
 Its purpose in life is for testing and to serve as a template for RA writers.

 NB: Please pay attention to the timeouts specified in the actions
 section below. They should be meaningful for the kind of resource
 the agent manages. They should be the minimum advised timeouts,
 but they shouldn't/cannot cover _all_ possible resource
 instances. So, try to be neither overly generous nor too stingy,
 but moderate. The minimum timeouts should never be below 10 seconds.
