rHGd8f07b16abfc: phabricator: add support for using the vcr library to mock interactions
Summary

I'll use this in an upcoming test. The decorator dancing in this is
more complicated than I'd like, but it beats repeating all this code
everywhere.

Queued the series, thanks.

Perhaps, it's easier to extend the registrar.command class instead. Another
option is to turn --test-vcr into a config knob, and hook somewhere in
dispatch.
