Title: autocomplete hosts from hosts sections in ssh-config

Zsh does autocompletion for /etc/hosts and hosts from the known_hosts but not for ssh-config profiles.
This plugin adds these to the hosts completion list. It also provides a feature to remove SSH keys from the known hosts file by profile name.
