Suggestion: Routing by query params

[Maximilan4]

Motivation: sometimes we need to create api which implements some external protocol, for example: amazon s3.
Current amazon api mostly works with query params, thats leads for need of using them on custom s3 implementation.
Amazon docs: https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetBucketLocation.html
Current echo api does not allow any routing by query part of request, or regular expression.
Also, seems like no way, to use custom router or extending router on echo instance, because Router is just a struct, but not an interface.
I think, it can be realized by next way:

• create Router interface, and echo method SetRouter(r echo.Router), which allow to customize router logic, if needed
• seems like current router is PathRouter, using by default
• optionally implement QueryRouter by query params and RegexpRouter by regex

I wanna use most echo features, but this thing does not allow to use this framework for non path/rest style api implementation.

Interface for router is coming in v5. See details about it here #2000
