AB#561 - Add waltti-alt

[VillePihlava]

Changes:

• Add waltti-alt
• Remove unnecessary double URL encoding
• Remove operationName (if two queries with operationNames are present, the run button opens a select view)

• Add support for headers in query parameters
• Change endpoint and API type logic
  • API type now always in URL never in local state
  • Endpoints can always be changed
  • API type uses the last one used OR finds a dev or prod endpoint
  • Added a test that requires either a dev or prod endpoint to be defined for all configs
  • example URL:

http://localhost:8080/graphiql/hsl/v2/gtfs/v1?urlVersion=2&apiType=dev&query=query+TestQuery+%28%24stopId%3A+String%21%29+%7B%0D%0A++stop%28id%3A+%24stopId%29+%7B%0D%0A++++name%0D%0A++++lat%0D%0A++++lon%0D%0A++++stoptimesWithoutPatterns+%7B%0D%0A++++scheduledArrival%0D%0A++++++trip+%7B%0D%0A++++++++route+%7B%0D%0A++++++++shortName%0D%0A++++++++%7D%0D%0A++++++%7D%0D%0A++++%7D%0D%0A++%7D%0D%0A%7D&variables=%7B%0D%0A++%22stopId%22%3A+%22HSL%3A1140447%22%0D%0A%7D
