XD-745 & XD-745 Use Spring batch admin
- Added spring batch admin manager dependency (1.3.0.BUILD-SNAPSHOT)
- Added BatchJobController & BatchJobExecutionController
 - Currently these controllers have list JobInfo/JobExecutionInfo
 - Map the requests to '/batch' to avoid conflicts with existing
   XD JobController
 - Created BatchJobLocator that extends ListableJobLocator
  - This will store job name & isIncrementable value for the job
 - Added DistributedJobService that extends batch SimpleJobService
   with unsupported methods that depend on runtime Job instance query
   from JobLocator
- Started HSQLDB in server mode
 - This will enable accessing the schema outside the JVM it is running
 - Removed the global bean config batch.xml and created batch config
   for AdminServer & ContainerLauncher
 - Added hsqldb.properties in config to set hsqldb related properties

XD-744 Fix review comments
- Added Profile based config to load batch config beans
- Added /batch/jobs/executions/{jobName} rest end point
- Fixed the type level RequestMapping to read 'batch/jobs'

XD-744 Updates to batch admin controllers
 - Added REST endpoints to GET jobExecutions & jobs by jobName
 - Added tests for BatchJobsController & BatchJobExecutionsController
Update UI to use the new batch admin api

- Enable the details request mapping
  Also, remove the '.job' suffix of job names when sending
- job info across the http request.
- update gitignore for sublime metadata files
- Change rest endpoint path
- Ability to display job instances
Fix BatchJobsControllerIntegrationTests
- Fix the jobName to have ".job" suffix as per the controller changes
XD-732: Enable JsonPropertyAccessor
Change test to accomodate future version of JsonPA
Add toString() to transform
Added tupleProjectionTest
XD-685 Add Plugin beforeShutdown callback

Allow Plugins to perform module cleanup using
Spring beans from the Module's context

XD-685 Support tap namespace in named channels

XD-685 Add bridge cleanup methods to ChannelRegistrySupport

XD-685 Add create/delete pub/sub channels to ChannelRegistry, disable tap method

XD-685 Create tap pub/sub channels on stream creation

- Create channel "tap:streamname.modulename" for each
module in a new stream, tapping into the module's output
channel. These tap channels can later
be used as named channels in other stream definitions.

- Supported syntax for tapping is now "stream create
mytap --definition ":tap:streamname > sink" or
":tap:streamname.module > sink". "tap:streamname"
will not work on a stream where source module is
a named channel (for now)

- Temporarily disallows tapping of named channels,
labels, or streams whose source is a named channel

XD-685 Remove support for tap commands

XD-685 Bind Rabbit FanoutExchange on inbound pub/sub
XD-818 Add timers for refreshing job definitions
 - Also updated .gitignore
Excluding MailCommandTests and will investigate root cause another time. See XD-826
XD-810 Fix stream deletion disconnecting named channel
from all streams

- On module removal, delete only the bridges bw
the named channel and the module's input/output
channels, instead of all named channel bridges
XD-810 polishing on merge
XD-823 - Added filter for Twitter deletes

XD-823 - changed to router
Created ExpandedJobInfo, which contains info about last execution.

UI now shows this.

Also, changed all references of scheduleJob to createJob

When no executions, UI now shows "no executions" over 
the entire line for the job
XD-824 ChannelRegistry now MessageBus

createInbound now bindConsumer

createOutbound now bindProducer

etc
XD-824 updated StreamPlugin
XD-820 a ':' can be embedded in a identifier thus allowing for namespaces.
