Major changes:
* Plumbing necessary for strict confinement with
the microstack-support interface
https://github.com/snapcore/snapd/pull/8926
* Until the interface is merged, devmode will be used and kernel
modules will be loaded via an auxiliary service.
* upgraded OpenStack components to Focal (20.04) and OpenStack Ussuri;
* reworked the old patches;
* added the Placement service since it is now separate;
* addressed various build issues due to changes in snapcraft and
built dependencies:
* e.g. libvirt requires the build directory to be separate from the
source directory) and LP: #1882255;
* LP: #1882535 and https://github.com/pypa/pip/issues/8414
* LP: #1882839
* LP: #1885294
* https://storyboard.openstack.org/#!/story/2007806
* LP: #1864589
* LP: #1777121
* LP: #1881590
* ML2/OVS replated with ML2/OVN;
* dnsmasq is not used anymore;
* neutron l3 and DHCP agents are not used anymore;
* Linux network namespaces are only used for
neutron-ovn-metadata-agent.
* ML2 DNS support is done via native OVN mechanisms;
* OVN-related database services (southbound and northbound dbs);
* OVN-related control plane services (ovn-controller, ovn-northd);
* core20 base support (bionic hosts are supported);
* the removal procedure now relies on the "remove" hook since `snap
remove` cannot be used from the confined environment anymore;
* prerequisites to enabling AppArmor confinement for QEMU processes
created by the confined libvirtd.
* Added the Spice html5 console proxy service to enable clients to
retrieve and use it via
`microstack.openstack console url show --spice <servername>`.
* Added missing Cinder templates and DB migrations for the Cinder DB.
* Added experimental support for a loop device-based LVM backend for
Cinder. Due to LP: #1892895 this is not recommended to be used in
production except for tempest testing with an applied workaround;
* includes iscsid and iscsi-tcp kernel module loading;
* includes LIO and loading of relevant kernel modules;
* An LVM PV is created on top of a loop device with a backing file
present in $SNAP_COMMON/cinder-lvm.img;
* A VG is created on top of the PV;
* LVs are created by Cinder and exported via LIO over iscsi to iscsid
which hot-plugs new SCSI devices. Those SCSI devices are then
propagated by Nova to libvirt and QEMU during volume attachment;
* Added post-deployment testing via rally and tempest (via the
microstack-test snap). A set of tests included into Refstack 2018.02
is executed (except for object storage tests due to the lack of object
storage support).

This reverts commit ce5e82e3191acb40b1ab801cde25333037d89bcb.
MicroStack cannot currently install due to a missing ovs-related
library. This is possibly due to recent changes in spacraft, or
possibly due to the workarounds for those changes. Regardless, it
appears that backing out the DPDK changes gets us back to a state
where we can install.
