Description

As many HBase users use binary row keys rather than strings to optimize memory consumption displaying an escaped string in the HBase shell isn't useful (and takes a lot of screen space)
Allowing user to provide a row key formatter as part of the scan\get commands would allow developers to display the row key in a way thats makes sense for them.

Example:
scan 'stats',

{ ROWFORMATTER => MyRowFormatter.new }

The row formatter simply gets the bytes array key and formats it to a string.
Its an easy change tomake with simple monkey-patching of the shell commands but I would be happy to see it as part of the shell itself.
