pcp updates - merge kenj (qa), lberk (json conv, buildbot, qa), Justin (nfsv42), Marko+Nathan (zabbix-agent)

Apart from CHANGELOG etc, QA updates only now. I'll be running QA all day
and tomorrow - depending how that goes, all week-end too. But if QA is good
then still planning for release on Friday.

I'm still seeing qa/1069 failures (pmrep - not sure why yet).

commit 29dc5e4e9d4990eb4fc00864ea868226bfb037e8
Author: Marko Myllynen <[email protected]>
Date:   Thu Nov 10 09:47:28 2016 +1100

    zabbix-agent: support zabbix 3.0.x and 3.2.x

    Add support for newer versions of zabbix, retaining compatibility with
older
    versions via dlsym checks. Original patch from Marko Myllynen, updated
with
    the extra dlsym checks by Nathan Scott.

    QA/1067 exercises this.

    qa/243: need slightly longer delay for second pmcd

    When testing "socket in use" errors, we need to wait a bit longer
    for the EADDRINUSE retry loops in libpcp.

    src/libpcp/src/auxserver.c: tweak EADDRINUSE diagnostics

    The recent change to add a "try 4 times before really reporting
EADDRINUSE"
    to overcome some race-in-QA situations was a bit too chatty (and caused
    qa/243 to fail), so move the reporting of each failed attempt inside a
    conditional, guarded by DBG_TRACE_DESPERATE.

    Update qa/798 to include nfsv4.2 metrics

    With the added NFSv4.2 client metrics, lets test that they're
    proprely reported with a new /proc/self/mountstats file

    Add NFSv42 parameters to linux PMDAs

    Fix libpcp_web json data type conversion

    Previously we were making the (incorrect) assumption that every
    numerical data type, if not a string or flag, was an int length
    variable.

    Add a flag_type where we can store the specific json_data type if
    needed.

    Tag and push newly created docker images

    Push the docker images to the regsitry so they can be publicly used for
    reproducing bugs the developer didn't catch themselves.
