chore(deps): bump tower-test from 0.3.0 to 0.4.0

[dependabot]

Bumps tower-test from 0.3.0 to 0.4.0.

Release notes

Sourced from tower-test's releases.

Tower 0.4.0

This is a major breaking release including a large number of changes. In particular, this release updates tower to depend on Tokio 1.0, and moves all middleware into the tower crate. In addition, Tower 0.4 reworks several middleware APIs, as well as introducing new ones.

This release does not change the core Service or Layer traits, so tower 0.4 still depends on tower-service 0.3 and tower-layer 0.3. This means that tower 0.4 is still compatible with libraries that depend on those crates.

Added

• make: Added MakeService::into_service and MakeService::as_service for converting MakeServices into Services (#492)

• util: Added MapRequest middleware and ServiceExt::map_request, for applying a function to a request before passing it to the inner service (#435)
• util: Added MapResponse middleware and ServiceExt::map_response, for applying a function to the Response type of an inner service after its future completes (#435)
• util: Added MapErr middleware and ServiceExt::map_err, for applying a function to the Error returned by an inner service if it fails (#396)

Looks like tower-test is up-to-date now, so this is no longer needed.
