feat(ops/modules): Add shared module for TVL cache

Browse source 
Add a shared nixos module for configuring whitby as a binary nix cache,
and refactor tverskoy to use this module.

This is enabled via an option to pave the way for including it as an
import in all depot-generated nixos configs at some point in the future.
