deleteFamily takes timestamp, should only take row and family.  Javadoc describes both cases
but only implements the timestamp case.
------------------------------------------------------------------------------------------------------------------------------------

                 Key: HBASE-762
                 URL: https://issues.apache.org/jira/browse/HBASE-762
             Project: Hadoop HBase
          Issue Type: Bug
          Components: client, ipc, regionserver
    Affects Versions: 0.2.0, 0.2.1
            Reporter: Jonathan Gray
            Priority: Minor
             Fix For: 0.2.1


The three version of deleteFamily in client.HTable (Text, String, byte[]) have varying descriptions
about whether they take timestamps or not.

public void deleteFamily(org.apache.hadoop.io.Text row, org.apache.hadoop.io.Text family,
long timestamp) throws IOException

    Delete all cells for a row with matching column family at all timestamps. 

public void deleteFamily(String row, String family, long timestamp) throws IOException

    Delete all cells for a row with matching column family at all timestamps. 

public void deleteFamily(byte[] row, byte[] family, long timestamp) throws IOException

    Delete all cells for a row with matching column family with timestamps less than or equal
to timestamp. 


These will become:

public void deleteFamily(org.apache.hadoop.io.Text row, org.apache.hadoop.io.Text family)
throws IOException

    Delete all cells for a row with matching column family at all timestamps. 

public void deleteFamily(String row, String family) throws IOException

    Delete all cells for a row with matching column family at all timestamps. 

public void deleteFamily(byte[] row, byte[] family) throws IOException

    Delete all cells for a row with matching column family at all timestamps.


Per Jean-Daniel's comment, deleteAll should then not permit families.  I'm unsure whether
this is currently allowed or not, but the documentation must be updated either way.

Will post patch after more thorough testing.
