This adds a check to see if plugin route URL is empty, and in such case
does not modify request schema and host of the request to be proxied.
This behavior is now the same as in the plugin proxy.
This adds support for using templated/dynamic urls in routes.
* refactor interpolateString into utils and add interpolation support for app plugin routes.
* cleanup and add error check for url parse failure
* add docs for interpolated route urls
