Comment 3 for bug 1477411

As we're in full control of the log configuration:

global
    log {{ local_host }} local0
    log {{ local_host }} local1 notice

so we should probably just switch {{ local_host }} -> /dev/log for all charms; this is templated via charm-helpers:

global
    log /dev/log local0
    log /dev/log local1 notice
