Release 0.9.0 Upcoming changes

[safaci2000]

As usual, the minor releases are releases where something previous behavior is being broken/deprecated. So 0.9.0 will add some breaking changes. Patch release try not to keep the release stable. aka 0.9.x

Security

A while back "secure" folder was introduced that has more meaning in K8s/Docker. It essentially can map out to a secret mount. All the data in that folder is sensitive information like: tokens, auth password, datasource credentials etc.

The idea is to pull anything sensitive out of the config file. At this point password/token have been more out in PR502. I'd like to move the S3 configs out as well.

This will leave importer.yml (or whatever you want to call it), to only configure behavior rather that auth.

Improvements/Changes:

Nice to have locally:

While the "secure" folder is a good first step, there is really nothing secure about it besides the name.

1. I've been meaning to add some plugin support to GDG for custom behavior. The secure auth is a great candidate for a very easy plugin that simply encodes/decodes a string and adds plugin support. [Optional]
2. Alerting is going to have some breaking changes. They are currently supported as global rules but no folder concept exists. I would like to add that ability as well
3. it would also be nice to rename importer.yml to gdg.yml. It would match the app name better. (We can still look for importer.yml for now and print a warning. We can drop importer.yml as the default name in 0.10.0)

Ideally I'd like to get all the breaking changes is 0.9.0. Any improvements can me iterated over to at least keep the 0.9.0 stable till we need to add some more invasive changes.
