wish: Unify image names

Currently we have different names for images name

• zephyr-blueprint-${blueprint} : for zephyr projects
• blueprint-${blueprint}-image : for linux projects

May I suggest we prefix name by oniro and use a consistant pattern (where flavour reflect kernel linux|zephyr) and blueprint (keypad|vending-machine|gateway...)

Some suggestions (most preferred comes first)

• oniro-{blueprint}-{flavour}-image
• oniro-{flavour}-{blueprint}-image
• oniro-{flavour}-{blueprint}-blueprint-image
• oniro-blueprint-{blueprint}-{flavour}-image
