In the CrossPoolMigrateCanMigrateFilter a WebException can be raised if the host cannot be reached to execute the API call that asserts is the VM can be migrated there. With these changes, we catch any exception (not just Failure) and mark the VM as not migratable (because we couldn't assert if it can be migrated to that host).
Also fixed other places where the same error might occur.

Further, specification of the network location of the installer files
has moved closer to the upgrade mode selection.
Also, moved the hotfix and upgrade related checks immediately after the
host liveness check.
