A user should be able to set RefreshTokenMaxReuse to 0 to enable RevokeRefreshToken
This value is about the amount of times a refresh can be reused, in which 0 is most often chosen value.
But in the code (see below) disables RevokeRefreshToken when you set RefreshTokenMaxReuse to 0.

	if refreshTokenMaxReuse := data.Get("refresh_token_max_reuse").(int); refreshTokenMaxReuse > 0 {
		realm.RevokeRefreshToken = true
		realm.RefreshTokenMaxReuse = refreshTokenMaxReuse
	} else {
		realm.RevokeRefreshToken = false
	}
