Investigate Jenkins Docker slave for Android

Investigation for building Jenkins Slave dockerfile that would include all required tools required to build android application.
We should extend base slave image and install all required tooling.
What we may look here is to use this image as base: https://hub.docker.com/r/jenkinsci/jnlp-slave.

Examples how slave images were build:

https://github.com/openshift/jenkins/tree/master/slave-maven

Example of the toolbox installations from here:
