[Bug 1543149] [NEW] Reserve host pages on compute nodes

 

Public bug reported:

In some use cases we may want to avoid Nova to use an amount of
hugepages in compute nodes. (example when using ovs-dpdk). We should to
provide an option 'reserved_memory_pages' which provides way to
determine amount of pages we want to reserved for third part components
