GDS pipeline restarted at LHO

The online h(t) pipeline has been restarted at LHO, following a software upgrade to gstlal-calibration (see https://versions.ligo.org/cgit/gstlal/tag/?h=gstlal-calibration-1.0.7-v1 and Redmine issue https://bugs.ligo.org/redmine/issues/4813#change-20027). We are applying a coherence uncertainty threshold of 0.004 for the online calculation of kappas, which is consistent with behavior observed during recent lock stretches (see the figure attached).

This update adds six new channels containing kappa values not gated by the calib_state_vector or by coherence uncertainties:

        [IFO]:GDS-CALIB_KAPPA_TST_REAL_NOGATE
        [IFO]:GDS-CALIB_KAPPA_TST_IMAGINARY_NOGATE
        [IFO]:GDS-CALIB_KAPPA_PU_REAL_NOGATE
        [IFO]:GDS-CALIB_KAPPA_PU_IMAGINARY_NOGATE
        [IFO]:GDS-CALIB_KAPPA_C_NOGATE
        [IFO]:GDS-CALIB_F_CC_NOGATE
 
It also removes two deprecated channels:
 
        [IFO]:GDS-CALIB_KAPPA_A_REAL
        [IFO]:GDS-CALIB_KAPPA_A_IMAGINARY

Note, the filters have not been updated for this pipeline restart. We are still using the filters documented in this aLOG: https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=30210.
