Layers and duplicated config options

[Junien Fridrick]

Hi,

I need to add the same config options to 2 different layers that are
used in the same charm. How does that work ? Should I add them the 2
layers and let "charm build" deal with it ? Or is there another way ?

My use case is to add the "nagios_context" and "nagios_servicegroups"
config options to both layer-docker and kubernetes-master /
kubernetes-worker. These options are used by the nrpe-external-master
relation, which I'm trying to add to the kubernetes-master and
kubernetes-worker charms.

Thanks !
