Add support for docker commit method (commit container with changes as new image)
ProgressStream and LogReader now read entire input stream

When processing a json stream, Jersey will not release the connection until
the entire input stream is read. This is a problem for our ProgressHandler
classes because if they receive an error from docker, they throw an exception
and stop reading. This causes Jersey to never release the connection, so you
will exhaust the connection pool if you encounter enough errors.

We had been calling close on the input stream, but this doesn't release the
connection because the stream we get from Jersey is of type UnCloseableInputStream,
where close is a no-op. So we now read the entire object instead.
Add logging lib to classpath in test scope

This lets us take advantage of log messages while running tests.
Setting level to warning, so they won't be noisy by default.

CircleCI: Ensure correct level of parallelism

This setting got flipped in CircleCI somehow and caused build failures.

Add a check for it at the very beginning of the build and print an
informative message in case it happens again.

Set longer read timeout for tests

* On our build agent, DefaultDockerClientTest.testSsl()
  takes longer than the default 30 seconds read timeout to complete
  the dockerSslDirectory's Dockerfile.
* Increase the read timeout for tests to 2 minutes.
