I don't think our Fedora/RHEL installation instructions are 100% up2date.

remi commented on https://github.com/mongodb/mongo-c-driver/commit/c8a9902fc58dbf63a6e3f7c8dbfc2e0cbedbc9d0#commitcomment-17332510 that there is no need to enable remi..

I don't know if that means only the yum-config-manager --enable remi is no longer needed, or if more things can be skipped.

We should test this and update the docs :]
