Adds autobackup (integrated, managed VM backups with automatic remote
filesystem mounting, included backup expiry/removal and automatic
full/incremental selection, independent from the manual "pvc vm backup"
commands) to the CLI client.
This is a bit of a large command to handle only inside the CLI client,
but this was chosen as it's the only real place for it aside from an
external script.
There are several major restrictions on this command, mainly that it
must be run from the primary coordinator using the "local" connection,
and that it must be run as "root".
The command is designed to run in a cron/systemd timer installed by
pvc-ansible when the appropriate group_vars are enabled, and otherwise
not touched.
Also fixes up the Debian packaging such that this works how I would
want, with proper module installation while leaving everything else
untouched. Finally implements automatic installation and removal of the
BASH completion for the PVC command.
1. Move to a YAML-based configuration format instead of the original
INI-based configuration to facilitate better organization and
readability.
2. Modify the daemon to be able to operate in several modes based
on configuration flags. Either networking or storage functions
can be disabled using the configuration, allowing the PVC system
to be used only for hypervisor management if required.
Completely restructure the daemon code to move the 4 discrete daemons
into a single daemon that can be run on every hypervisor. Introduce the
idea of a static list of "coordinator" nodes which are configured at
install time to run Zookeeper and FRR in router mode, and which are
allowed to take on client network management duties (gateway, DHCP, DNS,
etc.) while also allowing them to run VMs (i.e. no dedicated "router"
nodes required).
