Review request for hbase and jmhsieh.
Summary
-------
Added option to fix inconsistent table descriptors:
1. sideline the current .regioninfo file
2. create a new one with HTD from HBaseAdmin (meta, first entry)
3. offline the region and wait till it assigned again
This addresses bug HBASE-5801.

> Project: HBase
> Issue Type: Improvement
> Components: hbck
> Affects Versions: 0.90.7
> Reporter: Jonathan Hsieh
> Assignee: Jimmy Xiang
>
> Recently, we encountered a case where some regions in a table have different
> HTableDescriptor settings serialized into HDFS their HRegionInfo .regioninfo
> file. hbck expects all HTDs within a table to be the same and currently
> bails out in this situation.
> We need to either point out a proper set of actions for the user to execute
> or automatically convert the region to a common HTD (likely the most common
> on, or possibly the "first one".)
> Not sure if this requires reformatting data but may require closing and
> restarting a region.
> This issue is hbase 0.90.x specific -- 0.92+ keep all table info in a single
> .tableinfo file.
