Since we're no longer using the MiniLlama, we need to explicitly set
whether or not the cluster is pseudo-distributed. Impala needs this
information to correctly translate datanode addresses to a format that
Llama understands.
This change (adapted from one made by Casey) adds a method to the
frontend (callable via JNI) to get a configuration value from the Hadoop
configuration. We'll set that configuration value for local RM testing.

The hdfs-site template in CDH5 is different from the one we fine in CDH5. Specifically:
- It has entries that enable hdfs caching.
- It uses the correct parameter name for hdfs block locations timeout.

This should allow individual service components, such as a single nodemanager,
to be shutdown for failure testing. The mini-cluster bundled with hadoop is a
single process that does not expose the ability to control individual roles.
Now each role can be controlled and configured independently of the others.
