Vsock conflicts with factory, when both of them are enabled,
kata will try to create a new vm template which is useless,
thus it's better to return an error directly to let users know
that those two config cannot be enabled at the same time.

Add block_device_cache_set, block_device_cache_direct and
block_device_cache_noflush.
They are cache-related options for block devices that are described in
https://github.com/qemu/qemu/blob/master/qapi/block-core.json.
block_device_cache_direct denotes whether use of O_DIRECT (bypass the host
page cache) is enabled. block_device_cache_noflush denotes whether flush
requests for the device are ignored.
The json said they are supported since 2.9.
So add block_device_cache_set to control the cache options set to block
devices or not. It will help to support the old version qemu.

If VM factory templating is enabled (`enable_template=true`), error if
the configured image is not an `initrd=` one.
Also add a note to the config file explaining that a normal image cannot
be used - only initrd images are supported.
Fixes#948.

Moved the checking routines in `LoadConfiguration()` to a new
`checkConfig()` function for clarity.

Move the VSOCK handling code higher up so that all the checking code is
gathered together at the end of `LoadConfiguration()`.

Refactor the config related codes into a separated
package which can be shared with other cli programs
such as kata's shimv2.

In order to reuse the same scheme across several components of the
runtime repository, we need to factorize the code handling signalling
through a common package.
The immediate use case will be to use this package from both the CLI
and the network monitor.
