runtime Changes

Highlight changes:

  1. 9pfs in the guest is now mounted with cache=mmap option that provides better mmap related POSIX compliance.
  2. Guest entropy source can be configured via the entropy_source option and it defaults to the /dev/urandom host device.
  3. Guest max memory slot number can be configured via the memory_slots option.
  4. GPU device is now supported
  5. A new kata-netmon program is added and it is invoked by kata-runtime to monitor container netns on the host and relay any network changes to the guest.
  6. kata-runtime update subcommand now supports adding extra memory to a running container.
  7. vhost-net is now optional and can be disabled via the disable_vhost_net option.
