XD-1194 Handle boolean cmdLineOption default

Fixed 'jmxEnabled' CommonOption to use Boolean type instead of boolean
so that getter method could return null when the flag is not set and,
the setter would always set the appropriate precedence value when
resolving PropertySources.
Also note we have the application.yml setting XD_JMX_ENABLED to false hence
setter is always set with non-null value.

XD-1194 Remove null check on Boolean type

The getter method on XD_JMX_ENABLED in CommonOptions can never return false
as it can be either true or null.
Hence, made it to return value as is.

XD-1146 Add Async Request/Response to MessageBus

Add async request/response support to the MessageBus.

Initially to support batch partitioning over supported
transports, but generally applicable.

Simple partitioned job creates two partitions.

Add Code to JobPlugin.removeModule() to unBind the request/reply channels from the bus.

Add Rabbit Partitioned JobPlugin Test

Separate Partition Infrastructure allows user-defined jobs to import the infrastructure and just provide partitioner and tasklet beans.

Add Redis Message Bus Request/Reply Support

Fix Test After Rebase

Add more mocking to prevent NPE in test where we looked for the batch
partitioning channel(s).

Update to Batch 3.0.0.BUILD-SNAPSHOT

- includes spring-batch-integration
- Added new JobInstance 'instanceId' to Jackson Mixin
- fix some tests due to JobExecution constructor change
- Batch 3.0 no longer rejects duplicate executions when there are no parameters
    https://github.com/spring-projects/spring-batch/commit/ce16ad2b03b2370498e192ff7ad48052a4951f77#diff-325bf951caf9852e15e7490744cd9317L125
    fix tests for allow/disallow duplicate executions to add a parameter
- Remove the JobRepository DB before starting tests

Polishing

 - Remove requestorName from bindReplier
    Use a common name and identify the requestor/replier internally
 - Allow requestor/replier to bind in any order

Fix Excludes

Incorrect syntax for exclude of old s-b-integration.

XD-1224: Add gradle jacoco test coverage.

- Update gradle to version 1.10
- Enables the jacoco plugin for relevant projects.
- Adds an aggregate 'coverageReport' task at top level to accumulate all
the data for the sub projects.
- Removes the additional jacoco configuration for sonar. Sonar now uses
the coverage data files produced by the gradle plugin.
