"Smart" query route (/query) - MAPCO-4638

As part of the agreed architecture, We would like to add a /query route which will enable users, instead of querying specific route to get their data, to be able to query one "smart" route which will give them their wanted result. At first, we need to create a route which based on regexes, this route will "proxy" to the right desired route. For example, if user sent "tile ...", the route will proxy it to /tile route.

Start by locating the existing route definitions and the handlers for /tile and other specific routes. Define the regex-based matching behavior for /query, verify that matching requests proxy to the intended route, and add coverage for representative query patterns and unmatched requests.
