pmrep: handle multiple instances with pmi

[Marko Myllynen <myllynen@xxxxxxxxxx>]

I don't see PMI_ERR_DUPINSTNAME being available on the Python side
(like it is on the Perl side) so use the hard coded number for now
and switch to PMI_ERR_DUPINSTNAME once there.

This is a must-have in order to deal with metrics sharing indom.
