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. co-authored-by: MarioRobres <mrobres@opennebula.io> co-authored-by: Pavel Czerny <pczerny@opennebula.io> co-authored-by: Mirko Stojiljkovic <mstojiljkovic@opennebula.io> co-authored-by: Valentyn Bohdan <vbohdan@opennebula.io>
