CSIT-607 Optimize VIRL job scheduling algorithm
Optimize VIRL job scheduling algorithm based on available VIRL host capacity. Add IP pool availability pre-checks. - add quota based on max. allowe IPs and max. allowe VMs per virl - use one common bootstrap file instead of two separate files (one for ubutnut, another for centos) Change-Id: Ic40122a084624ff9c5eafa9f372b0451e857e29a Signed-off-by: Peter Mikus <pmikus@cisco.com>
