Today this protocols create method is just odd. Our only implementation
of it immediately casts to LinuxContainer, failing if it cannot do so. I
think what might make more sense is to pass in a configuration itself
with core parameters that we expect every vmm to be able to support, and
then in a specific implementation they can continue to cast this type to
a specific one to possibly extract some extra configuration values
(rosetta for VZ for example).
This rework will also make it simpler to support a Pod type, as the vm
setup is identical and simple.
This change adds documentation to quite a few existing public types that
didn't have a blurb before.
Additionally, this fixes a couple things that I think either didn't make
sense when going to document them:
- Rename ConnectionStream to VsockConnectionStream. This type only
functions for vsock connections.
- Deletes NsLock+Closure. This was not used anywhere.
- Rename ContainerizationOCI/Config.swift to ImageConfig.swift.
