[BUG] [scala-akka-client] Scala Akka client does not support arbitrary query string values

Created by: ameenhaq

Description

When generating an api with an endpoint that takes an arbitrary set of query string parameters, which is to be represented as Map[String, Any] in the client, the generated code tries to use a query parameter append method that does not support the Map[String, Any] data type.

Suggest a fix

Currently, it utilises a method withQueryParam which cannot handle a Map type.

def withQueryParam(name: String, value: Any): ApiRequest[U] = copy[U](queryParams = queryParams + (name -> value))

This can be supported by the inclusion of;

def withQueryParam(values: Map[String, Any]): ApiRequest[U] = copy[U](queryParams = queryParams ++ values)
