Improve the docker configuration detection (localhost vs 0.0.0.0 vs etc).

[karolh2000]

We need to improve the algorithm that detects if Pyrsia is already added/configured in the docker config. Right now the logic considers the localhost alternatives as independent but all of them should be equal so if any of them is detected in the docker configuration the command shouldn't suggest to update the configuration. The following hostnames should be consider "equal":

• localhost
• 0.0.0.0
• 127.0.0.1
• 0:0:0:0:0:0:0:1
• ::1
• the actual machine hostname
