ncm-cdispd to support test profiles

[msmark]

As per quattor/aquilon#34, quattor/CCM#112 and quattor/cdp-listend#13, ncm-cdispd should additionally monitor the test profile cache (cache_test_root in /etc/ccm.conf) for arriving test profiles. When they arrive all components should be dispatched with ncm-ncd -cache_root <cache_test_root> -configure -noaction -all which will execute all components with the latest test profile.

(Will ncm-ncd also need an option to tell it to post the results somewhere, see quattor/ncm-ncd#49?)

As discussed in the workshop, publishing results is best served with post-execution hooks.
