Disable prod/global,prod/phys01,prod/phys02 on cmsweb

As described in https://twiki.cern.ch/twiki/bin/viewauth/CMS/DBS3Transition I will disable the reader, writer, migrate views of prod/global, prod/phys01, prod/phys02 on cmsweb. The cronjob on cmsweb is disabling them around 3 PM CERN.

Cheers,
Manuel
