Option to ignore the check jira hook when jira is down

[wleona3]

Would be great to have an option to ignore the jira git hook when requests to the API throw timeouts or non-authentication 500 errors. Any thoughts?

Good idea. I've been bitten by this more than once too.

I won't be able to work on this in the near future, though. But I'm keeping it on my todo list. ;-)

If #77 gets merged, this could easily be implemented by OR-ing CheckJira with a simple plugin that only succeeds if Jira is down, unresponsive, etc.
