What type of PR is this?

/kind feature

What this PR does / why we need it:

Builds on #5548 to enable CAPA to allocate a dedicated host. This removes the requirement that a dedicated host exist prior to instance provisioning. A core assumption of this PR is that there is a 1:1 mapping between an instance and the dedicated host on which it runs. Nothing in this implementation precludes scheduling multiple instances to a given dedicated host, but that is not the goal of this initial implementation.

Special notes for your reviewer:

Checklist:

  • squashed commits
  • includes emoji in title
  • adds unit tests

Release note:

Adds support for provisioning an instance on a new dedicated host.

Hi @rvanderp3,
Thank you for picking this up.
I know the PR is still in draft but I wanted to add some suggestion at the start. Hope you don't mind.
