Increase libvirt/qemu.conf max_files and max_processes
When Nova and/or Cinder are using Ceph as backend, qemu will need
to open a connection and two threads for each and every Ceph OSD.
This change raises the max_files (set to 1024 by default) to 32768
and the max_processes (set to 4096 by default) to 131072. The max
number of FDs is per-process, while the max number of processes is
per-user. The values can be overridden via ExtraConfig, no params
are added to the templates.
A more detailed description of the values were chosen can be
found at: https://access.redhat.com/solutions/1602683
