qa/083: interoperability issue, need PCP >= 3.0 remote QA host

From the comment added to the test ...
    Need at least PCP 3.0 here, because there is an interoperability
    issue with older pmlc versions (e.g. 2.7.8) talking to a newer
    pmlogger ... the pmlc-pmlogger channel is fine, but when pmlc
    tries to contact the pmlogger's pmcd, if the pmlogger is using
    a local (Unix domain) socket, :local, then the wheels fall off.
