This Patch Set is meant to expose the 'query_interval' and
'task_timeout' parameters for Drydock tasks in Shipyard.
This will allow us to specify the values for a particular
site.
The corresponding changes for the Helm Chart are included in
this Patch Set as well.
It is also noted that the task has been updated to 'prepare_nodes'
and 'deploy_nodes' instead.
Task State can either be 'completed' or 'terminated'. These new
changes have been captured in this Patch Set as well.
