Track summary statistic of total HTTP response durations using a

Split up codebase into the packages @clsterio/lib, @clusterio/master,
@clusterio/slave, and @clusterio/ctl using lerna to manage them. This

size, and better separate the code into shared library, master, slave
and control.
Add users, roles and permissions and rework the authentication to use
separate user and slave tokens for control and slave connections
respectively.
Add commands for listing permissions, roles and users, and creating,
editing and deleting roles and users.
