#1653: [raster] ST_Transform & ST_Resample are confusing

Comment(by pracine):

 Now that ST_Transform has an alignment parameter, you could easily remove
 the confusion in ST_Resample() by renaming  _st_resample()to
 _st_gdalwarp() (what it truly is) and remove the SRID parameter from

 This way we have a set of usual functions each using the confusing GDAL
 Warp but avoiding the confusion. I don't know any other raster package
 mixing resampling and reprojecting in a unique function. I know
 reprojecting involves resampling but resampling certainly does not involve

 It's not because GDAL is confusing that we have to do the same...
