core: Storage domains failover never runs when all domains in problem

When blocking connections to all storage domains of pool at once,
reconstruct will never success as we don't have a working connection
to any domain, each running reconstruct will clear the domain timers,
meaning that the domains will never move to be inactive.

Basically the behaviour after this patch will be-
Successful reconstruct : clear jobs, problematic data and all events
from the queue.
Failed reconstruct: leave jobs, 'problematic' domains and vds data,
leave DOMAINFAILOVER/VDSCLEARCACHE events in the queue.

This patch adds the following changes:
*Event with the type of DOMAINFAILOVER/VDSCLEARCACHE should be added to
the queue when
reconstruct runs and also stay in the queue after unsuccessful
reconstruct.

*MarkPoolInReconstructMode which clears the timers and delete the
'problematic' data should be executed only if the reconstruct command
succeeded so that the domains will be able to move to inactive state,
I've removed also the no longer parameters and enum classes.
