# Details
This PR makes it allowable to leave out almost all top-level keys from
GitOps files. The only required keys are _either_ `name:` (for a fleet
settings file) or `org_settings:` (for a global settings file). Omitting
a key is identical to supplying it with no value.

## Testing
- [X] Added/updated automated tests
Updated the "missing all global keys test", and added some new tests to
verify that omitting the key was the same as supplying it with an empty
value.
- [X] QA'd all new/changed functionality manually
1. Ran `fleetctl generate-gitops` to get a clean set of GitOps yml files
2. Removed all removable keys from default.yml and ran `fleetctl gitops`
3. Ran `fleetctl generate-gitops` again into a different dir
4. Ran `fleetctl gitops` with the original files to get back to original
state
5. Cleared out all now-removable keys and replaced them with empty value
(e.g. `reports:` with nothing under it)
6. Ran `fleetctl generate-gitops` again into a third dir
7. Compared the files from the second and third generate-gitops runs to
verify that omitting the key had the same result as supplying it with an
empty value
8. Did the above steps with a fleet (i.e. non-global) .yml file.
