workspace_hack is needed to avoid recompilation when different crates
inside the workspace depend on the same packages but with different
features being enabled. Problem occurs when you build crates separately
one by one. So this is irrelevant to our CI setup because there we build
all binaries at once, but it may be relevant for local development.
this also changes cargo's resolver version to 2
Currently it's included with minimal changes and lives aside of the main
workspace. Later we may re-use and combine common parts with zenith
control_plane.
This change is mostly needed to unify cloud deployment pipeline:
1.1. build compute-tools image
1.2. build compute-node image based on the freshly built compute-tools
2. build zenith image
So we can roll new compute image and new storage required by it to
operate properly. Also it becomes easier to test console against some
specific version of compute-node/-tools.
