fixes for jclouds 1.7.0 (but no pom update until in maven central)
support networkName for GCE, and set the display name for JcloudsLocations to the provider if not overridden
pom update for jclousd 170
update QA project for guava 15 removed class (Ranges -> Range)
detect (and punish) deprecated images in gce
suggest turning off iptables in google compute
better os detection for jclouds locations, and better logging of creation process (reporting template and times); also gce live tests now just use the default as GCE keeps deprecating images, and mysql gce test added
