SQOOP-101. Sqoop build to use IVY for dependencies.

This change modifies Sqoop build to use IVY for retrieving HBase and
Zookeeper dependencies. Along with this update, the version number
for HBase and Hadoop have been incremented to match the CDH3 Beta 3
versions. Due to this, a couple of tests had to be modified in order
to accommodate the changed behavior of the Hadoop classes.
