HBASE-8693 [example] Use DataType API to build regionNames

This is an example of using the HDataType classes to manage
HRegionInfo's regionName. It could probably be taken a step further to
manage the MD5Hash as a LegacyBytesFixedLength, then the size of the
allocated buffer could be calculated with
HREGIONINFO_NEW_CODEC$encodedLength() instead of by hand.
