Provide option to set reserved_huge_pages
Provide option to set reserved_huge_pages in puppet-nova.
Ex. NovaReservedHugePages: ["node:0,size:2048,count:64","node:1,size:1GB,count:1"]
will reserve on NUMA node 0 64 pages of 2MiB and on NUMA node 1 1 page of 1GiB
When NovaReservedHugePages is set, "reserved_huge_pages" is set to the value of
NovaReservedHugePages. If NovaReservedHugePages is unset and OvsDpdkSocketMemory is
set, reserved_huge_pages value is calcuated from KernelArgs and OvsDpdkSocketMemory.
KernelArgs helps determine the default huge page size used, the default is set to
2048kb and OvsDpdkSocketMemory helps determine the number of hugepages to reserve.
when both NovaReservedHugePages and OvsDpdkSocketMemory are unset, then
NovaReservedHugePages set to default value [].

Sets the amount of hugepage memory to assign per NUMA node. It is

recommended to use the socket closest to the PCIe slot used for the
|

desired DPDK NIC. The format should be in "<socket 0 mem>, <socket 1

mem>, <socket n mem>", where the value is specified in MB. For example:

"1024,0".
