> Fix case-sensitive hostname check in region server

> Reporter: Tak-Lon (Stephen) Wu

>
> HBASE-27333 introduced a hostname validation check on RegionServer startup.
> This check is case-sensitive; if the Master reports the hostname in uppercase
> but the RegionServer resolves it in lowercase, the RegionServer aborts with a
> hostname mismatch error. This occurs even though DNS resolution is
> case-insensitive by nature and both names refer to the same host
