Change error message for too many CN strings to call out Managed Proxies
If a voms proxy has too many CN strings in the subject, jobsub_client prints out something like this:
ERROR Your user proxy, /opt/gm2pro/gm2pro.Production.proxy has DN=/DC=org/DC=incommon/C=US/ST=IL/L=Batavia/O=Fermi Research Alliance/OU=Fermilab/CN=gm2pro-gm2gpvm01.fnal.gov/CN=53687203/CN=3483874105/CN=1713665338/CN=2440479671/CN=3434234685/CN=2719291582 .This probably means voms-proxy-init has been used to refresh it too many times. The easist way to fix the problem is to remove the file /opt/gm2pro/gm2pro.Production.proxy and re-create it. The easiest way to re-create it is to re-submit your job after removing the file.
We should change that so that we explicitly tell users not to do this if they are using a Managed Proxy.
I'm making this high priority because it should be really simple.
