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.

See gh-28

Fixes gh-46

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.)

Fixes gh-44

Unfortunately only properties that have been set show up (unlike
/configprops), but possibly better than nothing. You can see some
in the Eureka server or in the customers sample (once it has
tries to contact the stores service and Ribbon is up and running).

Fixes gh-38

/v2/* -> /eureka/api/*

The prefix can't be /eureka because we use that for static
resources. Note that the "api" prefix gets passed to the
Jersey resources as a "version" (and defaults to "v2" when
it can't be parsed).

Fixes gh-41

I prefer to keep the actual components free of autowiring, so they
are easier to navigate in an IDE (i.e. you can see how they are
constructed)

 Specifically RequestParam, PathVariable and RequestHeader

gem install asciidoctor

create SpringClientFactory for ribbon to not fail on client creation if LoadBalancer is already created.  SpringClientFactory is not a static factory, but an instance factory.

Remove unused hystrix configuration classes.
