Metricbeat: Ensure canonical naming for JMX beans is disabled (elasti…

…c#7047)

Canonical naming for JMX beans in Jolokia is enabled by default, this

We were already setting these options in the url, but url parameters are
ignored in POST requests. This change adds these parameters as part of
the body.

(cherry picked from commit b9dbb1b)
