Previously, the config crate would get rebuilt each time the git state changed, which has a lot of fan out and makes the build take longer than it really needs to. This commit breaks out the version changing stuff to its own crate and then provides a runtime mechanism for assigning the version information back into the config crate. The env-bootstrap crate is responsible for setting that up.
