HAproxy health checks with authentication

Hi,

Your Authentication header is improperly sent.

Please run

curl -v https://user:password@rabbitmq01:15671/api/aliveness-test/%2F

and simply re-use the authentication header as built by curl.
With user:password string, it would be:

option httpchk get /api/aliveness-test/%2F HTTP/1.1\r\nAuthorization:\ Basic\ dXNlcjpwYXNzd29yZA==
