This adds the ability to augment or override the NATS auth system.
A server will send a signed request to $SYS.REQ.USER.AUTH on the specified account. The request will contain client information, all client options sent to the server, and optionally TLS information and client certificates.
The external auth service will respond with an empty message if not authorized, or a signed User JWT that the user will bind to.
The response can change the account the client will be bound to.

Tests that run on Travis have been split into jobs that run in their own VM in parallel. This reduces the overall running time but also is allowing recycling of a job when we get a flapper as opposed to have to recycle the whole test suite.
JetStream Tests
For JetStream tests, we need to observe a naming convention so that no tests are omitted when running on Travis.
The script runTestsOnTravis.sh will run a given job based on the definition found in ".travis.yml".
As for the naming convention:
All JetStream tests name should start with TestJetStream
Cluster tests should go into jetstream_cluster_test.go and start with TestJetStreamCluster
Super-cluster tests should go into jetstream_super_cluster_test.go and start with TestJetStreamSuperCluster
Not following this convention means that some tests may not be executed on Travis.
