Combine Limiter and Linearizer
...
Linearizer was effectively a Limiter with max_count=1, so rather than
maintaining two sets of code, let's combine them.

Use run_in_background in preference to preserve_fn
...
While I was going through uses of preserve_fn for other PRs, I converted places
which only use the wrapped function once to use run_in_background, to avoid
creating the function object.

Logging and logcontext fixes for Limiter

Add some logging to the Limiter in a similar spirit to the Linearizer, to help
debug issues.
Also fix a logcontext leak.
Also refactor slightly to avoid throwing exceptions.

Implement create_observer.
...
`create_observer` takes a deferred and create a new deferred that
*observers* the original deferred. Any callbacks added to the observing
deferred will *not* affect the origin deferred.
