[Feature Request] Limit total disk space usage of client recorder.

[timezombi]

After running the client recorder for less than 2 days of testing, the client-recordings directory had gone up to nearly 800GB of disk space usage! Is it possible to specify a maximum size for your client recordings directory, after which the oldest client recordings get deleted?

Normally I wouldn't think of asking for this kind of thing, but since there already exist a Cleanup script for Cache Server, I thought this might be easy to implement.
