[Rpm-maint] RPMN 4.18.0 rc1 released!

[Panu Matilainen]

More or less in planned schedule, here goes rpm 4.18.0 rc1.
Aside from the usual minor bugfixes here and there, the big news in this 
release is the (rather late) inclusion of the new, opt-in Sequoia-based 
OpenPGP backend.

For a more detailed idea of what changed since beta, see 
https://github.com/rpm-software-management/rpm-web/commit/be82c99de80ae47db48da9b7a27c89159b26ffcb, 
further details in git log of course.
