Convert Plugin to be compatible with Jenkins pipeline

[funtastix]

• DryRun was removed for this purpose and SimpleBuildStep implemented instead
• Simple usage example: "gradle tasks: 'clean assembleDebug', useWrapper: true"
• Works with Snippet Generator (which adds additional/unnecessary parameters)
• This enables gradle (wrappers) to be used easily cross-platform without scripts needed

Thanks for the contribution! Can you fix the tests?

[funtastix]

I will look into them. There seems to be additional tests running as all test had passed on my build machine.

The test failures appear to be on Windows only, so that could be part of the problem.

[funtastix]

This is what is confusing as I build on windows. I will hopefully figure it out.

@jvz I tracked the failures down to a parameter passing ending in '\'. I don't understand what this needs to look like and how my changes would have affected those tests. The parameter encoding is done via Jenkins util classes. I will try to get a comparison with and without my commits. It may be a good idea to add a new parameter test: Param="X;YZ\"

[jvz]

Almost sounds like the test failure might be unrelated then?

@funtastix I'll be closing the PR, given that there hasn't been any recent activity. Is the PR still interesting? If yes, please open a new one based on current main. Thank you!
