Updated image driver forcings and global files

    - Changed image driver VP from specific humidity (kg/kg) to kPa, and variable name from `shum` to `vp`
    - Fixed incorrect unit attribute of air pressure (`K` to `Pa`)
    - Update the image driver global parameter file template to 1) be consistent with VP variable name change; 2) be consistent with global options of the classic driver template
