[OE-core] [RFC] [PATCH] Provide users with project support status

[Ruslan Bilovol]

When OE/Yocto project goes through its lifecycle, there
is no any way to identify where it is other than go
to a Yocto wiki and look at current status.

Moreover, change from maintained to community maintained
end EOLing happens silently so users not always know
about that.

This patch aims to remove this gap. The status should
be changed so users can clearly identify at which point
it is now:
 Development -> Stable -> Community supported -> End Of Life

It is now printed during the build.

It will be also captured in the git history and
may be discussed over mailing lists during such a patch
reviews.

In the future this can be extended also to LTS when
we will have it
