We need a way to force sentry to check a specific mirror "right now" instead of having to wait for the next sentry pass. Right now it takes sentry about a half hour to check all the mirrors. If someone gets pulled, and the mirror admin tells me on IRC that they found the problem that caused them to get pulled and fixed it, I have no way to add them back in except to wait. This is a particular problem on release days with high-weight mirrors, because until they get added back in, it's additional load on everyone else because of how high they were weighted.
Using the command line and passing it a mirror_id is probably fine, fwiw.
Created attachment 360520 [details] [diff] [review] patch v1 Takes either a mirror_id or a baseurl as an optional second param after checknow. Only works in checknow mode (which is probably fine for my purposes).
This was committed to the production tag a while back.
