core: introduce NUMAPolicy and NUMAMask options
Make possible to set NUMA allocation policy for manager. Manager's policy is by default inherited to all forked off processes. However, it is possible to override the policy on per-service basis. Currently we support, these policies: default, prefer, bind, interleave, local. See man 2 set_mempolicy for details on each policy. Overall NUMA policy actually consists of two parts. Policy itself and bitmask representing NUMA nodes where is policy effective. Node mask can be specified using related option, NUMAMask. Default mask can be overwritten on per-service level.
