This path configures the connection properties used to connect to RabbitMQ management HTTP API.

The "connection_uri" parameter is a string that is used to connect to the API. The "username"

parameter is a boolean that is used to verify whether the provided connection URI, username, and password

are valid.

The URI looks like:

"http://localhost:15672"
