    Prevent init_host test to interfere with other tests

    The test_migrate_disk_and_power_off_crash_finish_revert_migration test
    needs to simulate a compute host crash at a certain point. It stops the
    execution at a certain point by injecting a sleep then simulating a
    compute restart. However the sleep is just 30 seconds which allows the
    stopped function to return while other functional tests are running in
    the same test worker process making those tests fail in a weird way.

    One simple solution is to add a big enough sleep to the test that will
    never return before the whole functional test execution. This patch
    proposes a million seconds which is more than 277 hours. Similar to how
    the other test in this test package works. This solution is hacky but
    simple. A better solution would be to further enhance the capabilities
    of the functional test env supporting nova-compute service crash / kill
    + restart.
