6c3642e9bc libvirt-guests: Add parallel startup and shutdown of guests
With this patch, it's possible to shut down guests in parallel. Parallel
startup was possible before, but this functionality was not documented
properly.

To enable parallel startup set the START_DELAY to 0.

Parallel shutdown has a configurable parameter PARALLEL_SHUTDOWN that
defines the number of machines being shut down in parallel. Enabling
this feature changes the semantics of SHUTDOWN_TIMEOUT parameter that is
applied as a cumulative timeout to shutdown all guests on a URI.

28d182506a save: support bypass-cache flag in libvirt-guests init script
libvirt-guests is a perfect use case for bypassing the file system
cache - lots of filesystem traffic done at system shutdown, where
caching is pointless, and startup, where reading large files only
once just gets in the way.  Make this a configurable option in the
init script, but defaulting to existing behavior.

* tools/libvirt-guests.sysconf (BYPASS_CACHE): New variable.
* tools/libvirt-guests.init.sh (start, suspend_guest): Use it.

d934bd0a58 libvirt-guests: implement START_DELAY
Allow libvirt-guests to stage a delay between guest startups,
to avoid system load caused by back-to-back startup.

2c090a555b Move libvirt-guests init script and config to tools
Since libvirt-guests init script and its configuration do not require
libvirtd to be running/installed, it was a bad idea to put them into
daemon directory. libvirt.spec even includes these files in
libvirt-client subpackage, which may result in build failure for
client-only builds when the whole daemon directory is just skipped.
