Add info logs around agent and tunnel registration
- Add info logs around agent and tunnel registration
This change set adds a bunch of info logs around agent and tunnel registration as well as tunnel handling and finding. It also adds some logging in the expiring hashes for GC.
Logging is not 100% consistent (like logging in ExpiringHashAPI and sometimes not) - I decided to log where we have most context for the issue at hand without refactoring.
Relates to #386 (closed).
