> As described in the doc (see HBASE-15531), we would like to start with user tables for
favored nodes. This task ensures FN does not apply to system tables.
> System tables are in memory and won't benefit from favored nodes. Since we also maintain
FN information for user regions in meta, it helps to keep implementation simpler by ignoring
system tables for the first iterations.
