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

[Jie Fu]

Hi Misha,

The default image for X86 is oraclelinux 7.6, which is also too old to 
run the JDK image I'd built on Ubuntu 18.04.
I's a bit inconvenient to use.

Shall we also update the default image for x86 like this?

If so, there is no need to update the testing doc.

Thanks.

Best regards,
