Export commonly used hypervisor fields and utility functions.
These need to be exposed to allow the hypervisor to be consumed
externally.
Note: This does not change the hypervisor interface definition.
Those changes will be separate commits.

This PR includes these optimize changes:
- Remove the dependency on the container engine.
The old code uses runc to generate config.json and
Docker to export rootfs, that will be heavy and need
additional dependency.
Using a fixed config for busybox image can avoid
the heavy processing above.
- Moved duplicate code to pkg/katatestutils package

When running the TestIoCopy test, on some occasions, the test
runs too quick, and closes the stdin pipe before the ioCopy()
routine start to read from it. This causes a SIGSEGV error.
To fix this issue, I am adding additional read/write tests before
closing the pipes. As the read operation waits for the writer to
be done, this actually synchronizes the threads and make sure
the final tests (with closed pipes) works as expected.

Display a pseudo path to the sandbox socket in the output of
`kata-runtime env` for those hypervisors that use Hybrid VSOCK.
The path is not a real path since the command does not create a sandbox.
The output includes a `{ID}` tag which would be replaced with the real
sandbox ID (name) when the sandbox was created.
This feature is only useful for agent tracing with the trace forwarder
where the configured hypervisor uses Hybrid VSOCK.
Note that the features required a new `setConfig()` method to be added
to the `hypervisor` interface. This isn't normally needed as the
specified hypervisor configuration passed to `setConfig()` is also
passed to `createSandbox()`. However the new call is required by
`kata-runtime env` to display the correct socket path for Firecracker.
The new method isn't wholly redundant for the main code path though as
it's now used by each hypervisor's `createSandbox()` call.

Add support for Hybrid VSOCK. Unlike standard vsock (`vsock(7)`), under
hybrid VSOCK, the hypervisor creates a "master" *UNIX* socket on the
host. For guest-initiated VSOCK connections (such as the Kata agent uses
for agent tracing), the hypervisor will then attempt to open a VSOCK
port-specific variant of the socket which it expects a server to be
listening on. Running the trace forwarder with the new `--socket-path`
option and passing it the Hypervisor specific master UNIX socket path,
the trace forwarder will listen on the VSOCK port-specific socket path
to handle Kata agent traces.
For further details and examples, see the README or run the
trace forwarder with `--help`.

Variables in rust will be dropped at the end of the function.
In function real_main the trace will be shut down by `tracer::end_tracing()`,
but at this time the root span is in an active state, so this root span
will not be sent to the trace collector.
This can be fixed by dropping the root span manually.

From the endpoints string described through the configuration file, we
build a hash set of allowed enpoints. If a configuration files does not
include an endpoints section, we assume all endpoints are not allowed.
If there is no configuration file, then all endpoints are allowed.
Then for every ttrpc request, we check if the name of the endpoint is
part of the hashset. If it is not, then we return ttrcp::UNIMPLEMENTED.

When the kernel command line includes a agent.config_file=<path> entry,
then we will try to override the default confiuguration values with the
ones we parse from a TOML file at <path>.
As the configuration file overrides the default values, we need to go
