#4870: /vsicloud support for passing config options
-------------------------+---------------------------
 Reporter:  pramsey      |      Owner:  pramsey
     Type:  enhancement  |     Status:  assigned
 Priority:  medium       |  Milestone:  PostGIS 3.2.0
Component:  raster       |    Version:  master
 Keywords:               |
-------------------------+---------------------------
 In order to access secured buckets in cloud objects, we need a way to pass
 in the various GDAL config options that allow security info to be added to
 requests.

 It's possible to add in environment variables when starting a back-end but
 that will be waaaay too coarse for most use cases.

 This ticket will add a per-session way of setting options that will be
 handed into each GDALOpenEx() call.

 Client API will just be (for example in S3):
 {{{
 SELECT ST_GDALOpenOptions(ARRAY[
   'AWS_ACCESS_KEY_ID=xxxx',
   'AWS_SECRET_ACCESS_KEY=yyyy'])
 }}}
 Those tokens will be passed to opens until the connection is closed, and
 they can be changed by the user at any time with another call to
 `ST_GDALOpenOptions()`.
