PJSM-212 Fix embedded XML in poller config (PSM)

When the Poller configuration was converted to JAXB, the config object
now contains the actual objects embedded inside parameters, instead of
an XML string that had to be hand-parsed.  However, the code inside
PollableServiceConfig was calling .toString() on the embedded config.
So, for example, an embedded page sequence would actually be returned
to the PSM as the string representation "PageSequence [Page=foo]" and
it would fail to monitor.  This likely affected other embedded XML like
the MTM as well.
