Change subject: core: fix incorrect value of migrating_to_vds ...................................................................... core: fix incorrect value of migrating_to_vds Since we retried to switch host to maintenance as part of the monitoring thread but before the updated data from the monitoring was saved, the migrating_to_vds could have been overridden and set back to its previous value. This bug caused NPE in VURTI#handOver method sometimes and sometimes it produced a VM which is not migrating with some wrong value in its migrating_to_vds field. The solution is to retry to switch host to maintenance in the after-refresh-treatment part of the monitoring.
