XD-1854 Remove Hadoop v1 support

- remove hadoop12, cdh4 and hdp13 distros

- change fs.default.name property to fs.defaultFS
XD-1856 Add option to specify fsUri for hdfs sinks
First attempt at stream state

Current thoughts:

1. ModuleDeploymentWriter.Result gets extracted into its own
top level class and renamed to Status.

2. When deploying a single module due to a container or leaving,
query ZK to obtain a collection of Status objects to pass along
to DeploymentUnitStateCalculator. This has XD-1591 as a prerequisite.

3. Status object needs to be written to ZK under
/xd/deployments/streams/<stream-name>/state. It should include
state and an optional error description.
checkpoint
Introduced DeploymentStatus to hold state and error information
Introduced DeploymentStatusRepository
Stream state recalculated upon container arrival/departure
Stream/job state recalculation after container arrival/departure
Pulled up $Result into ModuleDeploymentStatus
ModuleDeploymentStatus used to read/write module deployment state
Recalculate stream state upon leader election
