Change Details

We want to create a dedicated instance with a single executor to run the Android job. That boot the Android emulator which takes a full core and run some java process to execute the tests. The new labs instance should thus have 2 cores. We would want a puppet class that includes the required packages and `role::ci::slave::labs::common` which adds Java / Jenkins key etc. Once ready, the slave will need to be added to the Jenkins master via https://integration.wikimedia.org/ci/computer/ From there, the slave can be labelled with something like `AndroidEmulator` and we can get the job tied to that label so it will only run on this slave.
