This reverts commit 913cf3b4

Use "$node->no_install" to determine if install task should be queued. If no_install is set, run verify task.

Roll back check for $node->import when installing. Hostmaster will always need to be installed from the backend and then imported.

Save "drush_script" property to platforms and sites so that we can explicitly set drush to hostmaster.
