__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`

* Adding a test for target.go
Fixing some shutdown issues where tailers were stopped but didn't properly wait for the current position to be saved to file
Fixed an issue where an empty directory would lead to nothing being tailed

* adding more tests for target.go

* renaming quitComplete -> done per feedback
making PositionsFile private again, no reason for it to be public
removed unnecessary save of empty file on creation of positions file

* fixing lint errors

* cleaning up some comments
removing TODO around directories, added a test to verify behavior
some more cleanup per review

* fixing imports

fix container_name label

add external_labels support to promtail ksonnet

add container_name label to logs

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

* allow promtail target path to be a glob match

Promtail now expects __path__ to be a glob. All files that match
the glob expression will be tailed.  If new files are created that
match the glob, they will immediately be tailed.

* remove entry from positions file when file is deleted

* fix syncing the current positions to positions file

* handle file renames

When a file is renamed a "rename" and a "create" event are sent.
We need to treat the rename as a remove.  If the new filename matches
the path glob, then we will start tailing it when the "create" event
is reveived.
