This commits introduces a new framework for OpenNebula, it is based on
standard the OpenNebula middleware access driver (mad) model. Benefits
compared to the current implementation:
* Less overhead on API server and streamlined communications
* Ease integration with third party schedulers
* New "optimize" action to balance the workload of a cluster
* Embedded Plan Manager to apply optimization and deployment plans with
custom parameters for the scheduling window
* Custom optimization policies per cluster
This commits introduces 2 schedulers:
* Rank scheduler based on the match-making algorithm present in 6.x
series
* OpenNebula DRS an optimization algorithm based on an ILP solver for
placement and cluster optimization
Also new API calls has been added for onecluster as well as the CLI
updates to expose them.

* Cleanup oned in case of initialization error
* Fix monitoring after onemonitord restart. The code includes a "hook" point in case a driver is re-started so custom code can be executed. InformationManager sends the list of hosts and raft status in this case.
* B #5801: Update error msg, in case of duplicated drivers
All distros will now start to use qemu-kvm-one symlink generated upon
the opennebula-node package install via qemu-kvm-one-gen helper script.
The script will try to detect and use the proper qemu-kvm binary found
on that particular system.

* Add run and lock paths to self-contained
* Move oned lock to lock location
* vcenter monitor fifo is created in run location
* vcenter monitor lock is created in lock location
Ubuntu does not support restarting network and it needs to
restart each of the interfaces. In debian restarting the network
works and will continue to use the same method.
lsb_release command is not used as it is not installed by default
in debian.
Backup all log files with mv, move the backups from start() into start_one() and start_sched(), and expose the fact that the *_sched commands are supported
