[PATCH for-4.15] tools/xenstored: liveupdate: Increase the maximum number of parameters

[Julien Grall <julien@xxxxxxx>]

From: Julien Grall <jgrall@xxxxxxxxxx>

The longest possible command line for LiveUpdate is:

  liveupdate -s -t <timeout> -F

This is 5 parameters. However, the maximum is currently specified to 4.
This means the some of the parameters will get ignored.

Update the field max_pars to 5 so and admin can specify the timeout and
force at the same time.

Signed-off-by: Julien Grall <jgrall@xxxxxxxxxx>

This is a candidate for Xen 4.15. Without it, it would not be possible
to pass -F and -t together.

The change is only modifying behavior for XenStored LiveUpdate.
