Limit/Allow to specify an ephemeral port range used by consul-template client connections

We've recently encountered an issue with our application which was caused by its inability to bind a specific port (8081). Apparently, this port was temporary used by consul-template.

It would be nice to limit consul-template port binding to specific ephemeral port range to avoid conflicts with other applications.

Thank you.

No files, tests, or entry points are named. Start by locating the consul-template client connection setup and its existing port-binding configuration; determine how a configurable ephemeral port range would be exposed and verify that connections stay within the requested range without conflicting with other applications.
