Add dav endpoint version support

[PVince81]

If the endpoint version is specified in the constructor, use that.
Else read it from the capabilities call.

Looks like it's not possible to make it skip the whole class that tests DAV v1.

Skipping in setUp only seems to skip the first test. Then the other tests likely aren't running setUp again like in PHP, so the check is not done.

I could use a skip decorator but it needs to be applied on ALL tests.

Need to think of a better way...

[PVince81]

Now added a custom decorator to skip the test class in case DAV v1.0 is detected.
Let's see if that works...

[PVince81]

All tests passed now, will cleanup the history

@SergioBertolinSG is the OC env you're testing against clean ?

[SergioBertolinSG]

Maybe not, I can try with a different "clean" one.

[SergioBertolinSG]

OK, with a clean server it has worked all fine.
