Fix local letsencrypt (#389)

* local-dev: ensure pebble can access salt-master on the correct network

Something changed in networking that caused salt-master.vagrant.psf.io to resolve on the .60 address which emulates the "public network".

Since salt-master's pebble service is firewalled on that network, local pebble wasn't working

* move to shared `lego` state rather than each user
