Patch to add custom ping feature

Hi,

I've added a feature to mod_jk which provides an alternative to CPING/CPONG to determine if a worker is "alive". It allows you to configure a URI to test (using a GET request), and an expected HTTP status code.

worker.tomcat_default.custom_check_expected_status=200
worker.tomcat_default.custom_check_uri=/app/somefile

The reason for this is that we do rolling deploys across a cluster of Tomcat servers, and in the time the app is redeploying mod_jk continues to route requests to the Tomcat instance, resulting in 404's to our clients.

Is this something which would be considered for inclusion in mod_jk? Does it need more work?

Thanks and Best Regards,
