Changing label for cellular repair devices

Created a new label (cellular_repair) to be used to run the
cellular_StaleModemReboot test. Added this label to the appropirate
devices and changing the label in the suite_scheduler to reflect this
change. also added a logging message to the test as well as another
modem state string.
