PM: Weaker dependencies than PKGRECOM

[Artoria2e5]

RPM has three levels of dependencies, Requires, Recommends and Suggests.

Recommends will let PM try to resolve its dependencies, while Suggests doesn't.

Maybe suggests -> optional is better? Recommends is similar to suggests

@jiegec This is a set Package Manager function, not anything we can change here.

[Artoria2e5]

Wait, does dpkg has suggests?

I think this should be

# dpkg
[ "$PKGSUG" || "$PKGRECOM" ] && dpkgfield Recommends $PKGSUG $PKGRECOM

# rpm
$(rpmopttag Recommends $PKGRECOM)
# blah

[Artoria2e5]

And @jiegec , It's still possible to call it a different name in autobuild. If it sounds better, we should use it.

Yes it does. Refer to the packaging policy.

But should we?
