JCR-3928: Add pathStyleAccess flag

[pdenooijer]

Based on #47 but without the deprecations and lots of random commits.

This will resolve JCR-3928.

This capability is required because our on premise S3 solutions uses path style.

@reschke is there any change this gets merged? It would help out our project immensely as there would be no need to support a patched jackrabbit.

Of course.

I guess a unit test for this is hard to do?

[pdenooijer]

Thanks for the quick reply!

Back on topic: it won't be easy to unit test in the current setup, as the addition basically just proxies a setting to the AmazonS3Client class. As this is a dependency that is hard coded in the static Util class, it's not easy to mock/replace/etc.
