Remove bundled JAX-RS interfaces

Some apps like Netflix Ribbon use Jersey 1.x, and it means that we are stuck with JAX-RS 1.x. Can't use JAX-RS 2 libs as Jersey has JAX-RS classes inside jersey-core jar.

Solution: remove bundled JAX-RS classes and use standard Maven dependency mechanism instead. It will allow to drop in new JAX-RS 2 interfaces.
