openBalena: deviceType.getAllSupported() and config.getDeviceTypes() produce unexpected results

[pdcastro]

Expected Behavior

openBalena users expect that the CLI's balena devices supported command would list the devices actually supported by openBalena (issue balena-io/balena-cli#2281). In turn, it is somewhat expected that the SDK's deviceType.getAllSupported() or config.getDeviceTypes() methods would list the devices actually supported by openBalena when targeting openBalena's API server. The device types supported by openBalena are currently documented in openBalena's README:

https://github.com/balena-io/open-balena#differences-between-openbalena-and-balenacloud
Differences between openBalena and balenaCloud
Supported devices
openBalena: Raspberry Pi family, the Intel NUC, the NVIDIA Jetson TX2, and the balenaFin
balenaCloud: All the devices listed in balena's reference documentation

Actual Behavior

• config.getDeviceTypes() returns all device types supported by balenaCloud, not openBalena.
• deviceType.getAllSupported() - I couldn't test this because it currently causes an internal server error in the openBalena API, as reported in SyntaxError: Could not resolve relationship mapping from 'device type' to 'is default for,application' open-balena#121 . @thgreasi clarified that deviceType.getAllSupported() would probably return 0 results with openBalena.

@pdcastro but the SDK already reports as supported only the DT's that the API returns as known, which are based on what is found in the S3 bucket defined in the oB's docker-compose.yml .
I see your point but I'm almost tempted to say that this works as expected atm.
Maybe it's an issue of just setting the correct items in the balenaOS S3 bucket 🤔
