Unable to get cgminer work with pool
[Description of the issue]
Hi, I'm trying to connect a cgminer instance to minincore pool on my local machine. The pool is up and healthy, but I don't know how exactly to connect to pool via cgminer command.
I tried this:  
`./cgminer -o 0.0.0.0:3052 --user MY_RPC_USERNAME --pass MY_RPC_PASSWORD `  

when the pool config related section is:  
```
"ports": {
   "3052": {
     "listenAddress": "0.0.0.0",
...
```
And this is what I see in the miningcore log:

> [2019-01-30 16:25:49.8665] [I] [btc-1] [0HLK6LUSCB4M4] Accepting connection from ::ffff:127.0.0.1:53970 ... 
[2019-01-30 16:25:49.8665] [I] [btc-1] [0HLK6LUSCB4M4] Connection from ::ffff:127.0.0.1:53970 accepted on port 3052 
[2019-01-30 16:25:49.8704] [I] [btc-1] [0HLK6LUSCB4M4] Banning unauthorized worker for 60 sec 
[2019-01-30 16:25:49.8704] [I] [btc-1] [0HLK6LUSCB4M4] Connection closed 

Which means the `--user` and `--pass` parameters in the cgminer command is wrong. What username and password should be used when I want to connect to pool? The rpc ones? Or something eles?
