This adds ldap support to the grafana chart. This required updating the version of Grafana to 5.0, as this version allows for using configuration files to bootstrap the datasources and dashboards instead of using the grafana http api. This was a necessary change as using ldap for grafana presented issues trying to create the datasource via the http api This also adds a basic helm test for grafana. This test simply verifies whether the prometheus datasource configured exists and whether the number of dashboards reported by the admin api matches the number of dashboards expected Change-Id: I2e987cb425adba9f909722ffdb25b83f82710c4d
