Recent virsh/Docker network rework changed mcpcontrol (previously
a virsh-managed network) into a Docker-controlled network using
the 'bridge' driver.
As a consequence, Docker now isolates traffic from 'mcpcontrol'
network from the default Docker bridge network ('docker0') using
iptables rules that check input/output interfaces.
Yardstick (and any other Docker container hooked via 'docker0')
will not be able to ssh into Salt master due to this isolation.
One possible workaround would be to explicitly ACCEPT traffic
from 'docker0' going to Salt master. However, this is only
properly supported starting with Docker 17.06, while most CI hosts
and end users are still using 17.05 or older.
In older Docker releases, DOCKER-USER iptables table was not
avaiable, so injecting custom iptables and making them persistent
is not only complicated, it's also prone to subtle errors.
Another way to bypass the iptables rules is to route the packets
coming from our new Docker network via another bridge before
letting them find their way into 'docker0'.
This change adds a new route for the Salt master host (note that
MaaS container will not benefit from this) via the PXE bridge on
the jumphost (which can be either a real Linux bridge for baremetal
deployments or a virsh-managed network); adding one extra network
hop for each packet going between our 'mcpcontrol' Docker network
and 'docker0', effectively bypassing the Docker-enforced iptables
DROP.

Certain kernels (e.g. 4.4.0-101+ in Ubuntu) no longer automatically
ack the partition table update after `kpartx -a /dev/nbdX`, see [1].
To avoid another dependency on `parted` packages, use `partx` from
`util-linux`, which is already installed as a dependency of e2fsprogs.

Create 2 systemd services on the jumphost that will handle veth
pairs creation, respectively adding them to virsh/real bridges.
This allows us to set docker containers restart policy to 'always',
enabling persistent Salt Master/MaaS containers across jumphost
reboots.
NOTE: libvirt creates virtual networks async, hence the need for
retrying hooking veths to them.

- replace mas01 VM with a Docker container;
- drop `mcpcontrol` virsh-managed network, including special handling
previously required for it across all scripts;
- drop infrastructure VMs handling from scripts, the only VMs we still
handle are cluster VMs for virtual and/or hybrid deployments;
- drop SSH server from mas01;
- stop running linux state on mas01, as all prerequisites are properly
handled durin Docker build or via entrypoint.sh - for completeness,
we still keep pillar data in sync with the actual contents of mas01
configuration, so running the state manually would still work;
- make port 5240 available on the jumpserver for MaaS dashboard access;
- docs: update diagrams and text to reflect the new changes;

CentOS recently moved its kernel source RPM from the altarch subdir
to the same directory x86_64 kernel sources used to reside, so update
our script accordinly.

Explicitly set the ipv4_address for each network instead of relying
on ip_range allocation, which seems to fail / not be picked up.
While at it, use docker-compose 1.22 or newer to bypass slow Docker
network creation with 'macvlan' driver [1].

Make sure `virsh` and `virt-install` use the same connection URI.

lib.sh got pretty big over time, making it hard to maintain.
Since most of the functions defined now in lib.sh are only required
during build/deploy and not in state files, move them to a new file.
While at it, prepare for running build/deploy as non-root and
set a default connection string for virsh instead of using
user specific config in ~/.config/libvirt/libvirt.conf, which
caused end user experience issues in the past.
