hyperv: Cleans up live migration Planned VM

If an instance having iSCSI volumes attached is being
live-migrated, a Planned VM is created at the destination.
If the live-migration fails, the Planned VM is not cleaned
up at the destination.

This patch will ensure that rollback_live_migration_at_destination
is being called on live-migration failure for Hyper-V compute nodes,
which will clean up the Planned VM.

Revert "Revert "Fixes Python 3 str issue in ConfigDrive creation""

This reverts commit cf75bf2.

Fixes Python 3 str issue in ConfigDrive creation

ConfigDrive creation fails on Python 3 when writing metadata to file
due to the fact that in Python 3 only bytes can be written to a file.

This patch fixes this issue by replacing jsonutils.dumps with
jsonutils.dump_as_bytes and thus ensuring that all data that is to
be written is bytes and not str.
