Add "almanac.network.edit" and "almanac.network.search" API methods
Summary: Depends on D19334. Ref T13120. Ref T12414. These are pretty straightforward, but no one really has a use case for them anyway today so they're primarily just for completeness.
Test Plan:
- Queried networks with almanac.network.search.
- Created and edited networks with almanac.network.edit.
