[PATCH 1/5] KVM test: Include the preprocessing param migration_mode

[Lucas Meneghel Rodrigues <lmr@redhat.com>]

In order to include multi-host migration, add a pre-processor
parameter that will make the test start a VM in incoming
migration mode:

migration_mode = tcp

Will make the preprocessor start the VM in tcp -incoming mode.
