Filter on connection when getting role users

Feature: Filter on connection when getting role users.

Description: The “Get a role’s users” endpoint Auth0 Management API v2 returns a paginated list of all users. We would like to pass “q” query parameter (similar to get-users Auth0 Management API v2) that would allow us to filter the users on a connection, reducing the required queries. We can also get the list of users first and then get the roles per user but then we could run into rate limits. Ideally roles are optionally include in the get-users endpoint.

Use-case: We want to enable bulk user management in our application. Our user managers should be able to see a list of all users and what roles those users have. Then we want to implement some bulk update functionality as well.
