[libvirt] [PATCH v3 0/3] implement migrate-getmaxdowntime command

[Scott Garfinkle]

Currently, the maximum tolerable downtime for a domain being migrated is
write-only. This patch implements a way to query that value nondestructively.

Changes from [v2]:

* Resequenced and renamed patches
* Use updated qemuMonitorJSONGetMigrationParams for querying migration
  parameters.
