Basic virtio-fs support has made it upstream in the Linux kernel, as
well as in QEMU and Cloud Hypervisor. Let's go ahead and add it to the
standard configuration.
Since the device driver / DAX handling is still in progress for
upstream, we will want to still build a seperate experimental kernel for
those who are comfortable trading off bleeding edge stability/kernel
updates for improved FIO numbers.

James O.D Hunt: "But also, regexpContains() and
checkPathIsInGlobList() seem like good candidates for some unit
tests. The "look" obvious, but a few boundary condition tests would be
useful I think (filenames with spaces, backslashes, special
characters, and relative & absolute paths are also an interesting
thought here)."
There aren't that many boundary conditions on a list with regexps,
if you assume the regexp match function itself works. However, the
tests is useful in documenting expectations.

This was discovered while checking a massive change in variables.
The root cause for the error is a very long list of manual
replacements, that is best replaced with a $(foreach).
All individual variables in the output configuration files were
checked against the old build using diff.

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

When filtering annotations that correspond to paths,
e.g. hypervisor.path, it is better to use a glob syntax than a regexp
syntax, as it is more usual for paths, and prevents classes of matches
that are undesirable in our case, such as matching .. against .*
