start deleting old grib2
Reduce message from warning to just debug.

A NIDS product without a symbology block is not an error, so don't bother
warning about it.
Refactor to move
main: ucar.nc2.util.net to ucar.httpclient.
Also made ucar.httpclient be top-level
with its own pom.xml.
Reasons:
1. so we can include this code in opuls d4client
without having any other thredds dependencies.
2. part of the long term campaign to regularize
the structure of cdm.
