For users with out-db rasters in cloud object storage, the ability to set the config options for the VSI access is needed. In particular, the authentication keys need to be set for access to non-public rasters. For example, ``` SET postgis.gdal_vsi_options='AWS_ACCESS_KEY_ID=xxxxxxxxxxxx AWS_SECRET_ACCESS_KEY=yyyyyyyyyyyyyyyyy'; ``` This commit also removes the ST_GDALOpenOptions() function, which was never part of a release, in favour of the GUC approach.
