... instead of `#[path = ""]` importing it everywhere.
Make sure to use a diff review tool that understands file renaming 😅
(GitHub's diff view does.)
## Motivation
Transparency: I want to use the mocking functionality in the development
of a tracing component out-of-tree.
Additionally, this reduces the use of `#[path] mod` and file
multiple-inclusion, which aren't that great of a practice.
## Solution
The tracing test support module was already well self-contained, due to
being `#[path] mod` used in multiple places. As such, extracting it to
its own crate is rather mechanical, with no surprising blockers.
We additionally move the tracing-futures support module contents into
tracing_mock, for convenience. The one function which relies on
tokio-test is made optional.
It's a reasonable result for this functionality to stay unpublished, and
only used inside the repo, but pulling it out into a directly reusable
chunk instead of abusing the module system to reuse it via
multiple-inclusion is an improvement to code structure and
modularization.
