[Test Proxy] Align sanitizers, matchers, and transforms

[mccoyp]

Description

This PR initially was just going to be a fix to replace add_request_subscription_id_sanitizer with add_uri_subscription_id_sanitizer -- the former sanitizer either never existed, or was replaced with the latter sanitizer without me noticing. (In either case, my bad!)

After fixing this sanitizer though, I noticed that multiple sanitizers had been given a condition option since the time I added Python support for them. This PR adds that support where applicable.

Finally, this adds support for any other matchers, sanitizers, and transforms that are supported by the test proxy but haven't had Python support.

Overall this is great.

I'd like a quick offline conversation to discuss session vs individual recording settings, and then we can get this in.
