but still have a Zuul server with @Beans of type ZuulFilter added
automatically.

The default behaviour is now to strip the prefixes (global and
route-specific) by default. E.g.

zuul:
  prefix: /api
  routes:
    customers: /customers/**

Will forward /api/customers/101 to /101 on the customers service

See gh-43

We now support prefix stripping per service, e.g.

zuul:
  routes:
    customers:
      path: /customers/**
      stripPrefix: true

Will route /customers/101 -> /101 (on the customers service)

See gh-77

User can now specify zuul.routes.*.{path,url,serviceId} (with
"url" and "serviceId" mutually exclusive (and "location" is a
synonym) separately, or can use a one-one short form, like the
old style.

See gh-77

This allows mappings to be at the root and not have to be prefixed.  It also allows mappings to fall through to other handler mappings.  Patterns are now Ant-style via AntPathMatcher.

It works quite well locally actually. I tested with hostnames
127.0.0.1 and 127.0.1.1 and 2 servers running on localhost.

All static content is excluded in the Jersey config, so we can use
/eureka for the prefix to the Eureka API (i.e. /apps etc.)
