Fix some issue : register action from newer jenkins version, hack so that maven test can work...

Hello,

With a 1.593 version how jenkins, the junit attachment plugin was not working.
I added the junit plugin dependencies in the pom so that it could be registered
setup a snapshot view for image 
and add a hack that fix the url so that maven test (maven work by module) can display attachment.

It's not perfect, it works in my case... hope it can help...
