Allow for an IP address to be included in the connection configuration

We have had 2 situations recently where the DNS server at a customer has gone down, which means we can no longer connect to the machines via Control.

Automate has a configuration that allows for a DNS name and an IP address in the configuration, which means when internal DNS stops, the agent continues to operate. 

We would like the Control configuration to allow for multiple connection options(To match how Automate works).
