This change adds a healthcheck params dict to k8s charms for use by traefik via the ingress relation. It contains a path, interval, and timeout value. This allows traefik to detect down nodes and remove them from the loadbalancer rotation. Unless overridden in the charm, a default path of "/" is passed in the ingress relation. Interval and timeout are optional and will use default values of 30s and 5s, respectively, unless overridden in the charm. Some charms define a "/healthcheck" path in api-paste.ini which has been used in place of the default "/" path. Closes-Bug: #2077269 Change-Id: I355728f338e9a29fcf202cc629a977b49b2d8990
