* Add a scrape config for pods without name or app labels.

Signed-off-by: Tom Wilkie <tom.wilkie@gmail.com>

* rebase with master and update to prefer name label but fallback to controller name

* Update scrape_config to use pod controller_name in the job

If a pod has a "name" label we use that in the job name. Otherwise,
- If the pod was created directly by a controller (statefulset,
  daemonset, job) then we use that controller_name.
- if the pod was created by controller created by a controller
  (deployment, cronJob) then we use the parent controller name.

- add a scrape_config.sh tool that generates the scrap_configs
  for promtail.sh and helm chart from the ksonnet lib.

* Reduce duplication in jsonnet.

issue #313

kubelet creates a new log file when a container is restarted.
So we need to catpure all log files in the
`/var/logs/pods/<uid>/<container_name>/` dir.

__path__ is now expected to be a `glob` match, not a directory.  In k8s the "glob" expression needed is just the exact file path of the container log, which is `/var/log/pods/<podUID>/<container_name>/0.log`

fixes #190
Pods can have multiple containers. This fix ensures that we collect
logs for all containers.
