snapd debug without systemd activation

[Boris Rybalkin]

Disabling systemd socket  (snapd.socket) is just half a task. You do not
really want systemd to run your service (snapd.service) as you are running
it already in debug mode from IDE. Another thing, activation library
expects systemd env variables (LISTEN_PID, LISTEN_FDS) to be set, so there
should be fallback to standalone mode.

Again, I am actually asking how do you guys debug it from your IDE, as I do
not want to reinvent things?

If you are interested in some pull request for snapd to create these
sockets by its own when ran outside of systemd, let me know :)
