[TEST][RFC] #2 Added new tc to verify remote live migration.

Updates:
--------
Patch 2:
-------
1) Moved the VSMS object creation to vsmigration.py local_remote_migrate() fn.
2) Added check for domains on src and target, Undefined & destoryed domain on src and target
   depending on their existence.

Verified with KVM.
The test case will not pass for KVM since the guest information needs to have emulator
information without which the remote migration fails.
The support to pass the emulator information via VirtualSystemMigrationSettingData is
not yet available.
