specific user parameters' values for a host

This role has worked well in the context of *nix users in hosts of an IaC. But it's reaching some limits for LAN deployment.

A tipycal use case is a devops/sysadmin team who accesses all machines, and a main user in each machine, who may have several specific profile's data, but different machine from machine.

An idea could be to extend the data of cielito_host_username_list: not only a list of usernames, also allow user parameters, which values overwrite thoso global in cielito_users_data.
