Add region deletion tool
------------------------
Key: HBASE-3887
URL: https://issues.apache.org/jira/browse/HBASE-3887
Project: HBase
Issue Type: New Feature
Components: regionserver
Reporter: Ophir Cohen
Priority: Minor
A region deletion tool can be very useful to remove large amount of data.
For example, it can be used to remove all data older than specific date
(assuming your data sorted by dates) etc...
This tool should be something as follows:
Input: region key or (even better!) start & end key.
1. Split region to isolate the keys.
2. Disable the relevant regions.
3. Delete files from the file system.
4. Update .META. table.
