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)
