Import new console watcher to monitor guest console outputs, and will be
only effective when we turn on enable_debug option.
Guest console outputs may include guest kernel debug info, agent debug info,
etc.

With kata containers moving to 2.0, (hybrid-)vsock will be the only
way to directly communicate between host and agent.
And kata-proxy as additional component to handle the multiplexing on
serial port is also no longer needed.
Cleaning up related unit tests, and also add another mock socket type
`MockHybridVSock` to deal with ttrpc-based hybrid-vsock mock server.

We do not need the vc types translation for network data structures.
Just use the protocol buffer definitions.

[ port from runtime commit e1ee00d16ed621594a92ce0456eb048362962ff0 ]
Use systemd-cat to collect hypervisor output. The `systemd-cat` program
will open a journal fd and call `cat(1)` to redirect all the output to
the fd. This requires an extra binary to read from hypervisor stdout
(that has combined stdin, stderr and serial terminal). But because it is
cat the overhead is minimal and only is started on Kata debug mode.

Ingress traffic shaping is very limited, and the htb
qdisc discipline couldn't be applied to interface ingress traffic.
Here, we import a new pseudo network interface, Intermediate Functional Block (ifb).
It is an alternative to tc filters for handling ingress traffic, by
redirecting interface ingress traffic to ifb and treat it as egress traffic there.
