investigate possibility to remove java

[vdelendik]

we have to keep java for such bundle:

stf/lib/util/bundletool.js

Line 20 in 1f32ca0

function checkIfJava() {

let's investigate what might be done to remove this requirement. As I see keytool is required so we can try to install only this utility.
Also as variant completely disable/remove related functionality.

closing as won't fix. there is no sense to remove existing stf code and functionality
