release: 2.2.0

[jcvenegas]

Release 2.2.0

Changes

• Devicemapper storage: Added support to use device mapper volumes as storage devices instead mount a shared rootfs with 9pfs.
  • This allow to use a compatible posix file system and fix issues like qemu segfault (free(): invalid pointer) running dnf install  #669
• version: Update container image to 16020
• obs: Update packaging to include kernel config changes for xfs
• cc-oci-runtime.sh: Enable debug by default
• configure: Add warning when kernel or image is not found
• proxy: Better error message for too long socket path
• tests: metrics: formalise the metrics reporting methods
• build: Add option to install kernel and image
