Implement help text handling shortcuts in the Perl API. If we
find an existing metric help file, we use that. If not, we're
using any help strings registered in the add_metric/add_indom
calls. We keep those in global perl hash tables, indexed by
pmid/indomid, and have a custom help PDU handler (all neatly
hidden away from the PMDA perl scripts themselves).
