Comment 8 for bug 1504657

@mark: there will be "snap set core timeserver=123.456.7.89" (or some different option name, i'll discuss that in the team first), i just need the infrastructure in place first before being able to add a function to the configure hook for it.

i belive that autmatically translates to something like:

config:
  core:
    timeserver: 123.456.7.89

in yaml then (at least as i understood the config implementation)
