7c6aede5d4 config: Whitelist hypervisor annotations by name
Add a field "enable_annotations" to the runtime configuration that can
be used to whitelist annotations using a list of regular expressions,
which are used to match any part of the base annotation name, i.e. the
part after "io.katacontainers.config.hypervisor."

For example, the following configuraiton will match "virtio_fs_daemon",
"initrd" and "jailer_path", but not "path" nor "firmware":

  enable_annotations = [ "virtio.*", "initrd", "_path" ]

The default is an empty list of enabled annotations, which disables
annotations entirely.

If an anontation is rejected, the message is something like:

  annotation io.katacontainers.config.hypervisor.virtio_fs_daemon is not enabled

11b9c90cd8 annotations: Fix typo in comment
A comment talking about runtime related annotations describes them as
being related to the agent. A similar comment for the agent
annotations is missing.

b21a829c61 config: Protect ctlpath from annotation attack
This also adds annotation for ctlpath which were not present
before. It's better to implement the code consistenly right now to make
sure that we don't end up with a leaky implementation tacked on later.

6df165c19d runtime: add support for SGX
Support the `sgx.intel.com/epc` annotation that is defined by the intel
k8s plugin. This annotation enables SGX. Hardware-based isolation and
memory encryption.

For example, use `sgx.intel.com/epc = "64Mi"` to create a container
with 1 EPC section with pre-allocated memory.

At the time of writing this patch, SGX patches have not landed on the
linux kernel project.
The following github kernel fork contains all the SGX patches for the
host and guest: https://github.com/intel/kvm-sgx

1099a28830 kata 2.0: delete use_vsock option and proxy abstraction
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.
