This was the initial cut of the retry and delay meta parameters.
Instead, I decided to move the delay action into the common space
outside of the Watch resource. This is more complicated in the short
term, but will be more beneficial in the long run as each resource won't
have to implement this part itself (even if it uses boiler plate).
This is the first version of this patch without this fix. I decided to
include it because I think it has more correct event processing.
