[PULL,01/12] docs: Mark "gluster" support in QEMU as deprecated

Commit Message

According to https://marc.info/?l=fedora-devel-list&m=171934833215726
the GlusterFS development effectively ended. Thus mark it as deprecated
in QEMU, so we can remove it in a future release if the project does
not gain momentum again.
