## Testing
- [x] QA'd all new/changed functionality manually
Confirmed the traffic sequence with ngrok and DDM stats are as expected
in the osquery-perf logs:
### Adding a new DDM
* `DeclarativeManagement` command and Ack
* `tokens` request
* `declaration-items` request
* `activation` for the DDM
* `configuration` for the DDM
* `tokens` request confirms changes settled
* `status` request
### Remove/re-add DDM (no global change)
* `DeclarativeManagement` command and Ack
* `tokens` request
### Adding a second DDM
* `DeclarativeManagement` command and Ack
* `tokens` request
* `declaration-items` request
* `activation` for the new DDM only
* `configuration` for the new DDM only
* `tokens` request confirms changes settled
* `status` request
### Removing a DDM
* `DeclarativeManagement` command and Ack
* `tokens` request
* `declaration-items` request
* `tokens` request
* `status` request
### Remove all DDMs
* `DeclarativeManagement` command and Ack
* `tokens` request
* `declaration-items` request
* `tokens` request
* `status` request
