> Sometimes people want to reset the stream application sooner, but blocked by the left-over members inside group coordinator, which only expire after session timeout. When user configures a really long session timeout, it could prevent the group from clearing. We should consider adding the support to cleanup members by forcing them to leave the group. To do that, 
>  # If the stream application is already on static membership, we could call directly from adminClient.removeMembersFromGroup
>  # If the application is on dynamic membership, we should modify adminClient.removeMembersFromGroup interface to allow deletion based on member.id.
