Fix RemoteFileToHadoopTests

- Set application context explicitly for the LocalMessageBus inside the test
Use Msgbus binding to start

- The messagebus implementations, upon registration of consumer and producer from/to messagebus
the corresponding endpoints start.
  - Instead of directly calling the start() on adapter/consumer we can call the corresponding Binding's start()
     - This is in-line with the way the corresponding endpoints are stopped (using Binding's stop()) during
undeploy/destroy
XD-1595 Remove aliasHint in MessageBus

- Remove the use of `aliasHint` flag in MessageBus bindProduce/Consumer
- Fixed `LocalMessageBus` to use `QueueChannel` provider in case of named channels (p2p channel & job input channel)
- Fixed the tests
- Remove the methods isAliasedInput()/isAliasedOutput() in Stream/Job plugins
as they are no longer needed and the Source/Sink channel names are already set
in the DeploymentMetadata if the input/output channel name is aliased
XD-1614 Fix UTC endTime display

- The `endTime` attribute on job/step execution can be null if the job/step
execution is not yet complete by the time the test does the assertion
- Add `null` check on endTime in Job job/step execution display commands
- Fix test
XD-1620 Fix JobCommandTests

- Avoid using `JobExecution.getRows().get(0)`
  - Instead, get the matching jobExecution for the given job name and return the jobExecutionId for that row
- The same fix isn't needed for StepExecution list because they are retrieved on a given `jobExecutionId`
XD-1522: Allow only one label
XD-1365 Set ModuleDefinitions while deleteAll()

- When using AbstractDeployer.deleteAll(), the composed module definitions for the stream definition
is not set. Hence, the dependencies are not deleted from the ZK repository.
  - Fix `deleteAll()` to iteratively call delete(definitionName) which sets the ModuleDefinitions `beforeDelete`
- Remove calling `basicUndeploy()` at beforeDelete() in StreamDeployer
XD-1612 Simplify/Refactor UI controllers

- Remove unnecessary dependency injection when defining controllers
  - Inject only $scope as other dependencies are available from `xdAdmin.services`
- Create `XDCommon` service that returns the object representation for miscellaneous
methods such as logger, growl, timeout etc.
XD-1448 only log server errors at error level
