Release 1.3.0-rc1

Welcome to Kata 1.3.0-rc1.

Now the containers get entropy via virtio-rng. This helps to get a good quality of random number generation.
The agent has optional seccomp support, this will enable seccomp in the future in Kata. The ksm-throttler fixed install paths to do not have file conflicts with Clear Containers installations.
