Is your feature request related to a problem? Please describe.
Currently lnav supports tailling files on remote machines but it cannot be used for when the logs are managed by systemd (many are).

Describe the solution you'd like
support for remote tailing by systemd, perhaps with some prefix like user@host:journald:servicename

Describe alternatives you've considered
The only other viable option is to ssh and run journalctl queries and dump everything into local lnav
