Transfer the ownership of bluefield-gadget and bluefield-kernel snaps to Canonical

Additional context:

Regarding no stable-channel release, I consulted this post and my reasoning is quite similar: the snaps have not yet been a Generally Available solution. They are proof of concept that will be used as demonstration for Canonical’s partners. Releasing to stable channel will be certainly making people confused, although I am happy to release a 0.1/stable alternatively.

Please let me or my manager Alex know which approach you refer and which policy we should follow. We are happy to! Thank you!
