RFR(S): 8221342: [TESTBUG] Generate Dockerfile for docker testing

[mikhailo.seledtsov at oracle.com]

Thank you David, Severin and Jie for review and feedback.

I have fixed the issue pointed out by Severin, and also added comments 
to DockerfileConfig.java outlining usage of properties:

http://cr.openjdk.java.net/~mseledtsov/8221342.02/

I will see if I can get help testing this change on non-x64 platforms.


Thank you,

Misha
