Description

Our v2 framework(s) still lack parity with our v1 RequestHandlers in one important area: configuration and initialization.

v1 RequestHandlers have an init(NamedList) method which is called at creation time and allows RH's to handle any configuration attached to the relevant <requestHandler> tag in solrconfig.xml. This is most commonly used by administrators to override default values.

We should add similar functionality to our JAX-RS framework. (It's also a gap in the homegrown annotation framework, but as we're moving away from this it's probably a much lower priority to add there).
