Automatically enable the online hub

By default, crowdsec comes with an offline copy of the hub (see
README.Debian). When running `cscli hub update`, ensure switching from
this offline copy to the online hub.

To ensure cscli doesn't disable anything that was configured (due to
symlinks from /etc/crowdsec becoming dangling all of a sudden), copy the
offline hub in the live directory (/var/lib/crowdsec/hub), and let
further operations (`cscli hub upgrade`, or `cscli <type> install`)
update the live directory as required.
