dockertest 0.4 (#406)

* Updates to modern dockertest

* More updates to latest dockertest

* Update Cargo.lock to dockertest with handle restored

* clippy coordinator tests

* clippy full-stack tests

* Remove kayabaNerve branch for official repo's latest commit hash

* Update serai-client, remove reliance on the existence of a handle fn

* Don't use the hex encoding of unique_id in dockertests

Gets our hostnames just below 64 bytes, resolving test failures on at least
Debian-based systems.

* Use Network::Isolated for all dockertest instances

* Correct error from prior commit's edits
