Add an "auto-clusters" functionality to find new clusters automatically using search and some node attributes (addresses one checkmark on https://trello.com/c/YCRVRU9d/24-dashboard-for-spinning-up-and-tearing-down-ec2-instances)
Call individual routing rules sections one at a time so that we can put reqidel/reqadd lines after block lines and before redirect lines
Default to port 8080 if a server/cluster does not have a port specified
Partially revert e2bcfb9: Do not pass auto_clusters to backend (for real this time)
Test to make sure reqidel/reqadd rules get added in the right place
Create auto-cluster testapicluster and test that a backend gets created for it
