> Currently when namespace has quota, HMaster#normalizeRegions() skips the tables in the
namespace.
> However, performing region merge(s) wouldn't violate quota constraint.
> For region split, NamespaceAuditor#checkQuotaToSplitRegion() can be called to check whether
quota is about to be exceeded. If not, region split plan can still be executed.
