Ensure the tests in the local `logging` crate are run for all consumers
of it.
Additionally, add a new test which checks that output is generated by a
range of different log level `slog` macros. This is designed to ensure
debug level output is always available for the consumers of the
`logging` crate.
Fixes: #2969.

Return a guard variable from `create_logger()` which the caller can
implicitly drop to guarantee that all threads started by the async log
drain are stopped.
This fixes a long-standing bug [1] whereby the agent could panic with
the following error, generated by the `slog` logging crate:
```
slog::Fuse Drain: Custom { kind: Other, error: "serde serialization error: Bad file descriptor (os error 9)" }
```

Added new functions to convert to/from a log level name (like `debug`)
to/from the equivalent `slog::Level::Debug`.

The agent logger is useful and generic enough that it can be used by
other components, so move the agent logging package to below a top level
`pkg` to encourage re-use.
