rootless-containers/usernetes v20201118.0 on GitHub

Notable changes (#200, #203):

This release added support for systemd-delegated "cgroupfs" driver (v2 only). A pod is executed in a cgroup like /user.slice/user-1001.slice/user@1001.service/u7s-rootlesskit.service/kubepods/burstable/podb2d6a0c9-95d3-4372-80e0-bce249a26f95/7bb48caa579ee164fee4e0c072aaf430c2ec7b5dc13d512a5f19ce037de010ab on cgroup v2 hosts.
The installation script (install.sh) no longer needs --cgroup-manager flag.
cgroupsPerQos is now supported.
The patch for supporting "systemd" driver was removed.
RootlessKit now unshares PIDNS, IPCNS, and UTSNS as well as UserNS, MountNS, and NetNS. All namespaces except TimeNS are now unshared.

Note: still no cgroup support for CRI-O yet
