Fulfill Deployment Requirements

[dominiklohmann]

📔 Description

This PR serves as a merge base for multiple upcoming, related changes regarding the deployment and packaging requirements of VAST. It's done this way because the way CMake must be ran to configure and build VAST will change multiple times over the course of this PR, and we don't want to constantly break master.

I tested the current state locally and all my setups are working.

Note that it will be best to recreate the build directories. The caf and broker submodules must be initialized in their new locations under libvast/aux/....

After the approval I only squashed some PRs in the middle.
