Add a command to allow for setting various dynamic IOThread polling interval scope (poll-max-ns, poll-grow, and poll-shrink). Describe the values in the virsh.pod in as generic terms as possible. The more specific QEMU algorithm has been divulged in the previous patch. Based heavily on code originally posted by Pavel Hrdina <phrdina@redhat.com>, but altered to only provide one command and to not managed a poll disabled state. Signed-off-by: John Ferlan <jferlan@redhat.com> ACKed-by: Michal Privoznik <mprivozn@redhat.com>
