Drmaa library breaks when SCHEDD_HOST is used. #4629

The Drmaa library was using -name <hostname> with some, but not all, of
the HTCondor command line tools. If SCHEDD_HOST is set, then it wouldn't
talk to the same schedd for all operations.
Now, it never uses -name, so it will always talk to the default schedd.
Docs for Drmaa SCHEDD_HOST bug fix. #4629
Fixes committed in 8.2.3 for #4580 will not be announced in the manual,
as they are not completed.
