Relocated Fog script; waitUntil for IGI;

Moved the fog script out into *s* as it did not make sense (to me) to
have a separate folder for a single file, though I'm open to rebuttals.
Modified DAC config to check the HC param value also; added a
`waitUntil` for the IGI parameter as we don't want to check it until
it's populated
Removed param check in DAC

`f_param_hc` check in DAC is throwing error; but the value should be
defined. Removing for now, but this check should be done as DAC should
not execute on the HC if the param is not set to do so.
