Change image pull default policy to Always

- Loki and promtail are under heavy development, always pulling makes sure bug fixes are shipped

fixed promtail ds, it had deployment options

adding third party lib for Glob pattern matching which supports /**/ style subdirectory matching (#331)

* adding third party lib for Glob pattern matching which supports **
refactor promtail_test to be easier to read and include more tests

* Fix changes from PR and refactor to remove circular imports and make config consistent

* Adding an "integration" type unit test which tests promtail as a whole

* fixing a bunch of imports I munged
moved tailer to its own file
refactoring filetarget to make synclogic easier to follow and reused as much as possible

* update helm values yaml

- set persistence.enabled as 'false' as default since there is no pv as
default

- set persistence.storageClassName as 'default' since even if pv exists, pvc
still need storageClassName:

```
  Normal  FailedBinding  8s (x4 over 35s)  persistentvolume-controller  no persistent volumes available for this claim and no storage class is set
```

alpine:3.4 only contains a docker image for arm64, so building for other
architectures doesn't work. The newest alpine relases, 3.9, is therefore
better.
