While there appears to exist no pcpqa for this pmda, this episode is
another example of why pcp/pmda testing against real live host
software should be considered the gold standard (so we can notice
obsolescence or incompatibility), rather than synthetic/snapshotted
artifacts (which can give false assurance).

See also dsmith/dev's json pmda.  It may take even less work to write
some json-metadata for the interesting-version elasticsearch json
stats, than to update|rewrite the old elasticsearch pmda.
