Ensure nagios enable_livestatus is true for thruk-agent to function

[zxhdaze]

When relating thruk-agent to nagios as a subordinate with the container:juju-info, Thruk-agent should be able to configure/override the nagios "enable_livestatus" config to be "true", as thruk-agent does not function without enable_livestatus=true.

This bug is to track creation of the relation between nagios-charm and ~canonical-bootstack/charm-thruk-agent to enable this automatic relation-based configuration.

(by afreiberger) This feature wont likely make it into these charms, as the change is non-trivial.

Tagging juju-lint project to identify when nagios enable_livestatus is not true.

(by afreiberger) update contrib rules in juju-lint to ensure nagios enable_livestatus=true
