Modernize most Conduit console interfaces

Summary:
Ref T603. Ref T2625.

Long chain of "doing the right thing" here: I want to clean this up, so I can clean up the Conduit logs, so I can add a setup issue for deprecated method calls, so I can remove deprecated methods, so I can get rid of `DifferentialRevisionListData`, so I can make Differntial policy-aware.

Adds modern infrastructure and UI to all of the Conduit interfaces (except only partially for the logs, that will be the next diff).

Test Plan…
