Using Runtime execution modes

The Qiskit Runtime has two execution modes, Batch and Session, that allow for grouping multiple jobs. You can include M3 calibration jobs in these modes using the runtime_mode argument in mthree.M3Mitigation.cals_from_system. For example:

from qiskit_ibm_runtime import Batch
from qiskit_ibm_runtime.fake_provider import FakeCasablancaV2
import mthree

backend = FakeCasablancaV2()
batch = Batch(backend=backend)

mit = mthree.M3Mitigation(backend)
mit.cals_from_system(runtime_mode=batch); # This is where the Batch or Session goes

Note that if no runtime_mode is set, and the passed system is an IBM backend, then jobs are submitted in Batch mode automatically. This mode is NOT closed by default, allowing users to include additional jobs. This mode can be accessed via mode = mit.system.get_mode()
