Hello Kata Kats,

I'm proud to announce that we have reached another milestone for Kata
Containers by releasing the 1.3.0 release and 1.2.2 stable release.
All users are recommended to upgrade.

The 1.3.0 release highlights following features:

- Network hotplug: Sandbox network can now be dynamically changed by
the "kata-runtime network" subcommand. This allows customized CNI
plugins to create more Kata-native network endpoints.

- Network monitoring: a new kata component (kata-netmon) is added to
monitor container netns on the host. Now CNI hooks to dynamically
change the network setup of a running container, and "docker network
connect" works with Kata Containers.

- Network multiqueue support: Network cards are added to to the guest
with multiqueue support. It allows Kata Containers to gain better
network performance.

- Memory hotplug: "kata-runtime update" subcommand can now add extra
memory to a running container.

- Better container memory constraint support: containers in the same
sandbox can be constrained by memcg inside the guest.

- GPU support: both GVT-g and GVT-d GPU devices can now be used by
Kata Containers.

- Architecture/arm64: add GICv4 or higher support.

The 1.2.2 stable release also sees several important fixes and users
who want to stick with stable-1.2 branch are recommended to update.

Thanks to all contributors who have helped to make it happen!

Cheers,
Tao
