Hive runtime for Twitter Ambrose (initial commit)

Hi,

I'd like add Hive runtime support for this great tool.
Some notes about the implementation:
- The job progress notification is done by using Hive's (0.11.0+) Hook interfaces
- One Hive statement represents one workflow. All statements are executed in a script
  sequentially, those which result in a MR job are visualized. At the end all workflows can be replayed
- Currently Ambrose uses Hadoop 0.22. Note, that Hive is not compatible with this version,
  therefore I set Hadoop 0.23.x for  Ambrose-hive (also tested with Hadoop 1.x.x)

More information can be found in hive/README.md.
I hope you'll find this extension useful, any suggestions, remarks..etc are very welcome.

regards,
Lorand
