Add a basic Conduit log view

Summary:
The conduit access to Differential kind of sucks and we want to break
back-compat in order to fix it (see D1114).

To make it easier to pull this off, I want to build out the Conduit logging a
bit so administrators can identify which users are making deprecated calls.

We should probably build a little more infrastructure around this too (API
versions?), but this is at least a reasonable step forward which gives us more
insight into the use of Conduit and more tools to smooth the deprecation
process.

This initial commit is super basic but the interface currently says "stuff",
I'll build this out a little more in a bit.

Test Plan: Looked at call logs.
