[SPARK-5015] [mllib] Random seed for GMM + make test suite deterministic
Issues:
* From JIRA: GaussianMixtureEM uses randomness but does not take a random seed. It should take one as a parameter.
* This also makes the test suite flaky since initialization can fail due to stochasticity.
Fix:
* Add random seed
* Use it in test suite
