recheck/reverify comment_filter is too loose

As far as I know there was never any intention in our design that you would be able to use "recheck" commands to trigger specific systems, and to date no standardized syntax for this has been proposed. I understand this has grown as an ad-hoc convention among some third-party CI systems, but no guarantees were made around supporting this.

Jeremy,

ok, sure. but it was a quite useful functionality. just IMO.

While I don't think this is a bug, it's worth discussing a concrete syntax for this which can be consistently implemented across multiple participating CI systems, preferably without overloading the currently ambiguous "recheck" syntax. I would suggest that this probably depends on completing Anita's CI account naming standardization efforts first, however, and then should be taken through proper Infra design channels by interested parties (perhaps the unofficial Third-Party CI team would like to collaborate on a proposal).

This is also being discussed in http://lists.openstack.org/pipermail/openstack-infra/2014-August/001681.html for those who wish to chime in.
