meta-phosphor: add a base image recipe
Much like core-image-base, add a base OpenBMC image
obmc-phosphor-base-image.
This is essentially CORE_IMAGE_BASE_INSTALL +
packagegroup-obmc-apps-extras (which is empty by default).
At time of writing, obmc-phosphor-base-image is an abstract thing and
doesn't make any specific statement about content. The initial intent
is twofold:
1 - Provide a base image upon which space constrained users can "build up"
their image content by appending to IMAGE_FEATURES in place of the
current practice of "tearing down" obmc-phosphor-image by _remove-ing from
IMAGE_FEATURES (The Yocto layering implementation prefers appending over
_remove-ing for maximum layer compatibility).
2 - Over time, a carefully curated set of IMAGE_FEATURES would be added
(there aren't any at the moment) that provides content that most
users would expect by default.
