EPEL-ANNOUNCE Retire mongodb from EPEL7

[Patrik Novotny]

Hi,

there's intend to retire the mongodb package from EPEL7 [1]. As for
the MongoDB license change[2], we are not able to backport patches,
which leaves us shipping basically unmaintained release.

Since that is generally not a good idea, we are deciding on retiring
the package.
