Add test cases and arbitrary test case setup function (#127)

<!--- Note to EXTERNAL Contributors -->
<!-- Thanks for opening a PR! 
If it is a significant code change, please **make sure there is an open
issue** for this.
We work best with you when we have accepted the idea first before you
code. -->

<!--- For ALL Contributors 👇 -->

## What was changed
Add arbitrary test case setup function to set up non-standard test cases
with environments that are not represented in
`TemporalWorkerDeploymentStatus`.

Add test cases:
- manual rollout -> deploy inactive worker but no routing config changes
- first progressive rollout -> target immediately becomes current
- nth progressive rollout -> progressive rollout steps are respected
- test that controller scales down deployments for inactive versions of
failed target


## Why?
We want coverage of these scenarios want to build out our ability to add
more scenarios

## Checklist
<!--- add/delete as needed --->

1. Closes #33 

2. How was this tested:
This PR adds tests
The manual mode test and the scaling down inactive versions test needed
Controller code changes to pass, so I saw them fail, thereby ensuring
that the test actually tests what I say it does.

3. Any docs updates needed?
TODO: Possibly mention this in definition of Inactive version status,
actually. Or in description of Worker Controller Scaling Behavior
