Make sure default push_messaging_over_quota_behavior is
TEMPORARY_ALLOW_LIST_TYPE_FOREGROUND_SERVICE_NOT_ALLOWED.

CTS test expects the default push_messaging_over_quota_behavior in frameworks is TEMPORARY_ALLOW_LIST_TYPE_FOREGROUND_SERVICE_NOT_ALLOWED, but somehow the test device has its push_messaging_over_quota_behavior changed and it causes the CTS test failure. The reason push_messaging_over_quota_behavior is changed might because a ongoing experiment.

Also after configuring the device_config push_messaging_over_quota_behavior,
sleep a few seconds to let it become effective in frameworks code,
otherwise the test case testPushMessagingOverQuota may be flaky.
