XD-923 Add Option to Auto Declare/Bind DLQ

Add bus-level and consumer-level option `autoBindDLQ`.

When `true` when a consumer is bound, the bus will declare
the DLQ with name `xdbus.name.dlq` and bind it to exchange
`xdbus.DLX`. (xdbus is configurable using the `prefix` property).

Also, change queue and exchange declarations to perform passive
attempts first; this avoids issues if the user has pre-declared
the elements using incompatible arguments.

Test Polishing

Use prefix 'xdbustest.' for test entities.
Unbind the consumer.
Remove all test entities.
Move filepollhdfs to config/ format
XD-2114: Job stuck in "deploying" state when no containers are available

Introduced a new test for job state transitions.

Modified JobDeploymentListener to ensure that job state is correctly
updated if a job deployment fails due to the lack of containers.

Addressed review comments
XD-2269: Remove module definition display
XD-1880 Count integration tests

Last tests to implement before removing test scripts.

Code Polishing
Removed separate deployer thread

In commit a272d51 a separate thread for stream deployments was
added in order to avoid slowing down the Curator thread responsible
for cache updates. However this may lead to a race condition where
the Curator thread (from handling a container arrival event)
may deploy a module at the same time as the dedicated initial deployment
thread.

The fix is to remove the separate initial deployment thread and
force all deployments, regardless of source, into a single thread.
