This PR adds a block in the dendrite config for the services to bind to. The microservices should bind to the addresses in the bind block, and will be contacted at the address in the listen block.
This fixes an issue with the microservices and kubernetes services.
We were escaping the URL before performing any pattern matching on it.
This meant that if you sent data that URLdecoded to a "/", it would count as
a "/" in the URL, potentially causing a 404. This was causing some flaky tests
with some randomly-generated query parameters.
Now, we keep URLs encoded while doing the pattern matching, and only afterwards
do we URL decode each query parameter individually before passing them to their
respective handler functions.
github.com/gorilla/mux was also updated to v1.7.3 to fix a bug with URL encoding and subrouters.
