[pixels-daemon, pixels-cache, scripts] start with NUMA interleave=all

[bianhq]

Currently, pixels daemon is not started with NUMA interleave=all. For that pixels cache is loaded by a single thread, the memory consumption among numa nodes are not balanced.
This may not only impact the memory access performance, but more seriously, it may cause swap insanity problem.

However, further optimization of NUMA re-balancing and NUMA-aware task scheduling are left in future works.
