## Details
This PR adds the ability to manage labels via GitOps. Usage is as
follows:
* If a top-level `labels:` key is provided in the global YAML file
provided to GitOps, then any labels in this list will be created (if
using a new name) or updated (if using an existing name).
* If no top-level `labels:` key is provided, no changes will be made to
labels. This allows backwards-compatibility; customers won't blow away
all of their labels if they don't immediately use `labels:` in their
YAML
Additionally, some new validation has been added so that label usage is
checked prior to application. This means that when the gitops command is
run, it will verify that any labels referenced elsewhere in the YAML
(e.g. by software installers or mdm profiles) exist, and will bail with
an error message if they don't.
## Testing
**Test label deletion**
1. Add some labels via the UI
2. Run `fleetctl gitops --dry-run` with a default.yml file _without_
`labels:` in it, and verify that it doesn't say it will update or delete
any labels
2. Run `fleetctl gitops` with a default.yml file _without_ `labels:` in
it, and verify that it doesn't modify or remove your labels
4. Run `fleetctl gitops --dry-run` with a default.yml file with
`labels:` in it and nothing underneath, and verify that it says that it
will delete your labels
4. Run `fleetctl gitops` with a default.yml file with `labels:` in it
and nothing underneath, and verify that it removes all your labels
**Test label create/update**
1. Add a label "foo" via the UI
2. Run `fleetctl gitops --dry-run` with a default.yml file with two
`labels:` in it, one named "foo" and one named "bar". Verify that the
output says that one label will be created and one will be updated.
2. Run `fleetctl gitops` with a default.yml file with two `labels:` in
it, one named "foo" and one named "bar". Verify that the two labels now
exist in the UI with the configuration you specified.
**Test label usage**
1. Add a label "foo" in the UI.
1. Run `fleetctl gitops --dry-run` with a default.yml file _without_
`labels:` in it, where a software installer or mdm profile uses the
"foo" label via `labels_include_any`. Verify that the output doesn't
complain about unknown labels.
1. Run `fleetctl gitops --dry-run` with a default.yml file _with_
`labels:` in it with nothing underneath, and a software installer or mdm
profile uses the "foo" label via `labels_include_any`. Verify that the
output complains about unknown label "foo"
1. Run `fleetctl gitops --dry-run` with a default.yml file _with_
`labels:` in it with a "foo" label defined underneath, and a software
installer or mdm profile uses the "foo" label via `labels_include_any`.
Verify that the output doesn't complain about unknown labels.

- [X] Input data is properly validated, `SELECT *` is avoided, SQL
injection is prevented (using placeholders for values in statements)
- ~[ ] Added support on fleet's osquery simulator `cmd/osquery-perf` for
new osquery data ingestion features.~
- [X] Added/updated tests
- ~[ ] If database migrations are included, checked table schema to
confirm autoupdate~
- ~For database migrations:~
- ~[ ] Checked schema for all modified table for columns that will
auto-update timestamps during migration.~
- ~[ ] Confirmed that updating the timestamps is acceptable, and will
not cause unwanted side effects.~
- ~[ ] Ensured the correct collation is explicitly set for character
columns (`COLLATE utf8mb4_unicode_ci`).~
- [X] Manual QA for all new/changed functionality
- ~For Orbit and Fleet Desktop changes:~
- ~[ ] Manual QA must be performed in the three main OSs, macOS, Windows
and Linux.~
- ~[ ] Auto-update manual QA, from released version of component to new
version (see [tools/tuf/test](../tools/tuf/test/README.md)).~
