Style question on IMAGER_INSTALL

[Jan Kiszka <jan.kiszka@siemens.com>]

Hi all,

since we have sophisticated imagetypes support with per-type chroots, we
also have more options how to model imager dependencies:

IMAGER_INSTALL += "${GRUB_BOOTLOADER_INSTALL}"

WIC_IMAGER_INSTALL += "${GRUB_BOOTLOADER_INSTALL}"

IMAGER_INSTALL:wic += "${GRUB_BOOTLOADER_INSTALL}"

Which of those should we try to promote today, consistently in code and
documentation (and our own downstream layers)? Not the first one, I
would say, as it potentially injects dependencies into image types that
have no need for it. The second one probably only exists today because
of historic reason, I suppose. Should we move everything to the third
style and start to deprecate WIC_IMAGER_INSTALL?
