Add Travis CI support for the Python SDK

This change adds the ability to run the SDK test suite using Travis CI.
Specifically, it includes:

1. Using the Travis CI Docker capabilities to download a container
running Splunk pre-built to run tests.

2. Fixes to "setup.py test" to properly log which test is running and
also exit with a non-zero status code on errors/failures.

3. Fixes to various tests to make them work properly and not make
any assumptions on the running system.
