Didn't.  Looked at the ping/pingd and nginx RAs.  Grepped and googled a
bit.  http-mon.sh isn't in the Ubuntu resource-agents 1:3.9.2-5ubuntu4.1
package (as found ubuntu 12.04) and I never pulled from github.  Pulled
together http_ping.

It works, it's complete from my point of view.  It can't start or stop
anything, but it can monitor any http (or https) service that's not
managed by the cluster and set attrd attributes based on that to aid
location rules.
