Make match filterName between pfsConfig and flux calibration

Flux calibration reads broad-band information from pfsConfig. But the current flux calibration assumes different names from targetDB/gaiaDB, and therefore we need to unify the names to run flux calibration. We change filterName in flux calibration and use ones of targetDB and gaiaDB.
 
{{filterName}}s passed down from targeted and gaiaDB to pfsDesign and pfsConfig are:
[band]_ps1 for PS1
[band]_gaia for Gaia
 
Similarly, we can use {{filterName}}s of [band]_hsc and [band]_sdss for HSC and SDSS, respectively.

EDIT

PIPE2D-1110-change-filter-names.py has to be run in order not to break the integration tests and weekly tests after this branch is merged to the main branch.
