[PATCH v2 17/22] tests/qtest/migration: Split CPR tests

[Fabiano Rosas]

Move the mode/reboot test into a separate file to hold all the CPR
tests. Currently there's just one test, but we're adding more CPR
modes and the feature is different enough from live migration that
it's worth it to have a separate file for it.
