- Add a new element 'guest-agent' for image building. This element is
used when dev_mode=false, so that the trove code is downloaded into
the image during the building phase rather than during the guest
agent initialization.
- Improve trovestack sub-command 'build-image'.
./trovestack build-image ${datastore_type} \
${guest_os} \
${guest_release} \
${dev_mode}
- Improve documentation.

This element clears out /etc/resolv.conf and prevents dhclient from populating it with data from DHCP. This means that DNS resolution will not work from the amphora. This is OK because all outbound connections from the guest will be based using raw IP addresses.
In addition we remove dns from the nsswitch.conf hosts setting.
This has the real benefit of speeding up host boot and configutation times. This is especially helpful when running tempest tests in a devstack environment where DNS resolution from the guest usually doesn't work anyway. This means that the guest never waits for DNS timeouts to occur.
