rP6556536d0615: Allow repository cluster bindings to be marked as not "writable", making them…

Summary

Depends on D19356. Fixes T10883. Ref T13120.

Add a "writable" property to the bindings, defaulting to "true" with a nice dropdown.
When selecting hosts, allow callers to request a writable host.
If the caller wants a writable host, only return hosts if they're writable.
In SVN and Mercurial, we sometimes return only writable hosts when we could return read-only hosts, but figuring out if these request are read-only or read-write is currently tricky. Since these repositories can't really cluster yet, this shouldn't matter too much today.

Test Plan

Without any config changes, viewed repositories via web UI and pushed/pulled via SSH and HTTP.
Made all nodes in the cluster read-only by disabling "writable", pulled and hit the web UI (worked), tried to push via SSH and HTTP (got errors about read-only).
Put everything back, pulled and pushed.

See T13611. This was broken by D20775 (September 2019) until D21576 (February 2021).
