Add path argument so we can customize where settings.xml will be stored

Hi

I would like to add path argument to your action, so I can decide where my settings.xml will be stored :)

I will be very glad for review and comments :)

Thx for collaboration.

I know it is simple change .. but for consequence please add simple test something like

 mySettings =  path.join(testHomePath, 'mypath,,,');
 process.env['INPUT_PATH'] = mySettings;
 
 settings.generate();

 and check if mySettings exist

Thanks for feedback :)! I added one test and squash commits :)!
