Minor changes to the drift monitor threshold updater script:
The log files are now recorded to: "/opt/rtcds/userapps/release/sus/common/medm/sus_driftmon_logs/", and have the following file name structure: SUSDRIFT_{OPTIC NAME}_{START_TIME}-{DURATION}.log (e.g. SUSDRIFT_ALL_1107199664-15.log, SUSDRIFT_MC1_1107199664-15.log)
