Add a --now option that starts the program instantly, instead of waiting for a
connection on the socket. This is useful, for instance, when developing:
Say I have a Rust, socket-activated web service. I can test it with:
systemd-socket-activate -l 8080 --fdname=http cargo run
However this delays running the service (which potentially involves compilation)
to when I try to connect to it, which wastes time. Since it delays compilation,
I also don't see any warning or errors in the code until it gets a connection
either.
The name's now a bit of a misnomer, since starting the service immediately isn't
really socket activation, but oh well ¯\_(ツ)_/⁻
