Support for multiple values under the same query parameter name

[andreyfilyakov]

Is your feature request related to a problem? Please describe.
In our project we have some requests which require multiple values for the same parameter name, e.g. <base_url>?param=value1&param=value2&param=value3. We tried to use QueryMap annotation to achieve our goal, but it works with Map<String, String> only, so it's not possible to set multiple values for the same key.

Describe the solution you'd like
It'd be ideal to support Map<String, List<String>> for QueryMap annotation.

Hi @andreyfilyakov , you can do that with Query and a List
suspend fun testQueryWithList( @Query("param") name: List<String>)

I will think about adding additional ways to enable that

Hi @Foso! Your idea should work, but what if I have dynamic set of parameters with dynamic list of values for each parameter like this:

• param1: [value1, value2, ..., valueN]
• param2: [value1, value2, ..., valueN]
• ...
• paramM: [value1, value2, ..., valueN]
