Measure metadata downtime during live-migration
This patch adds to test_server_connectivity_live_migration
a verification of the downtime that affects the metadata service during
a live-migration.
A script is executed on the VM instance in background while the instance
is live-migrated. After live-migration is completed, the script output
shows the duration of the metadata outage and the test compares that
duration with a configured threshold.
