This PR covers issue #618 for supporting additional routes on the Dashboard in Bindings column. This makes it easier to navigate to endpoints that you access frequently like /swagger.

Is there anything I can help with to get this going?

Some design feedback: Routes should be an array instead of a semicolon delimited String

Any traction on this? Looking like it's closer now :)

@ante-maric Looks good to me, and rather handy! Thanks for the submission! The only change I've made is to use blocks for the binding spans, as it starts to get hard to read with many routes.

@ravipal Since I've made changes myself, can you review as well?
