- Updates travis to run karma
- Adds some actual tests

Sample build success: https://travis-ci.org/djvirgen/kubernetes/jobs/61567253

Note: My branch is currently up to date with master but all the Go stuff is failing in Travis. Not sure why Go is failing, but the Karma stuff is running OK. I've also verified that when a Jasmine test fails, Travis will fail the build (see [this build](https://travis-ci.org/djvirgen/kubernetes/jobs/61567666) here).

Corrects error in https://github.com/GoogleCloudPlatform/kubernetes/commit/19224deb04ea0f7b5003c9d29e9c841d7b1b6152 on linux cpus with hyperthreading (we need to pass the results of `cat /proc/cpuinfo | grep 'core id'` through uniq before counting the lines).
Also checks that we found more than 0 lines (cores) and defaults to the result of nproc in case we didn't (necessary for processors without the core id field, so far only observed on a raspberry pi).

Revert "E2E: Soak test and Functional tests for K8Petstore "

For examples/meteor: update README, minor fixes.

Introduce an 'svc' segment for DNS search

Add a flag to disable legacy APIs
