Change drbd-pacemaker to recommend instead of require pacemaker on EPEL8/EPEL9
    
    pacemaker is in the RHEL highavailability channel in EL8 and EL9.  EPEL
    packages dependencies must be in the "target base" (baseos, appstream, crb).
    Weak dependencies are allowed on packages from other channels, so use a
    recommends instead of a requires on EPEL8 and EPEL9.
