Modifies SwitchStats schema + removes Cloud Functions
DISCOv2 is introducing a new field into each sample, counter, to record raw SNMP counter values (instead of just the diff from the previous value). This release modifies to the switch data type schema to include this new field.
Additionally, this release modifies update.go so that the switch schema can be modified automatically by scripts, instead of someone having to manually modify tables.
Finally, this release removes all Cloud Functions pieces from the Travis configuration, as they were no longer used.
