Ensure static agents are listening on accessible ports when health checks enabled

[chadlwilson]

Description

As noted in #106, the static agent health checks require additional configuration to work as they no longer listen on 0.0.0.0 by default for security reasons when running in other environments outside a Kubernetes pod sandbox.

This will automatically change the configuration if they are enabled.

Relevant issues

• fixes Healthcheck does not work out of the box #106
