Out of tree classes need to re-implement _get_all if baseurl != /artifactory

ProjectUser and some other objects require /artifactory to be stripped from drive.

The current base _get_all() method referred to below:

https://github.com/devopshq/artifactory/blob/a95d10e9264677a409a508ae30b967f68d82e699/artifactory.py#L2090

has explicit knowledge about which classes should have /artifactory stripped. Putting this knowledge in the base class doesn't seem right since it can't know the proper behavior of all sub-classes.

Alternatively, maybe check a properly that is set by the implementor that triggers behavior. (eg: self.baseurl)

Using an optional argument to _get_all() won't work because in the lazy=True case, .read() doesn't know whether /artifactory should be stripped (again unless it is overridden).

Thoughts?
