logtree: implement

This implements logtree, as per go/logtree .

Some API changes are present, the design doc will be updated to reflect
these and the rationale behind the changes.

This implementation is missing 'raw' log functionality, this will be
added in a diff on top (as the implementation is trivial, but we want
to keep this diff as simple as possible).

Test Plan: covered by tests
