test: move cluster tests to parallel

Two cluster tests have recently changed so that they are no longer
resource intensive. Move them back to parallel.

test: make test-cluster-disconnect-leak reliable

Previously, test-cluster-disconnect-leak had two issues:

* Magic numbers: How many times to spawn a worker was determined through
empirical experimentation. This means that as new platforms and new
CPU/RAM configurations are tested, the magic numbers require more
and more refinement. This brings us to...

* Non-determinism: The test *seems* to fail all the time when the bug
it tests for is present, but it's really a judgment based on sampling.
"Oh, with 8 workers per CPU, it fails about 80% of the time. Let's try
16..."

This revised version of the test takes a different approach. The fix
for the bug that the test was written for means that the `disconnect`
event will fire reliably for a single worker. So we check for that and
the test still fails when the fix is not in the code base and succeeds
when it is.

Advantages of this approach include:

* The test runs much faster.
* The test now works on Windows. The previous version skipped Windows.
* The test should be reliable on any new platform regardless of CPU and
RAM.

cluster: ignore queryServer msgs on disconnection

It avoids the creation of unnecessary handles. This issue is causing
intermitent failures in `test-cluster-disconnect-race` on `FreeBSD`
and `OS X`.

The problem is that the `worker2.disconnect` is being called on the
master before the `queryServer` is handled, causing the worker to
be deleted, then the Server handle is created afterwards. Later on,
when `removeWorker` is called from the `exit` handler, there are no
workers left, but one handle, thus the `AssertionError`.

Add a new `test/sequential/test-cluster-disconnect-leak` based on
`test-cluster-disconnect-race` that creates lots of workers and fails
consistently without this patch.
