[UWS] Correct the way the URL interpreter is used: at initilization with a HttpServletRequest, the full URL until the base URI should be saved + In UWSService, the used URL interpreter was a class attribute, which is a bad thing (this object is shared by several threads).

[UWS,TAP] Review the exceptions and logs management + Add log file rotation (with a configurable rotation frequency)

Remove useless and blocking test (when url-pattern in web.xml is set to the root: /*) in the UWS URL parsing. + Add very basic check on its implementation
