Current behavior

When a seed peer address is malformed, instead of logging to error and continuing or exiting, p2p currently panics.

Expected behavior

The microservice should log the error and continue, if possible.

Steps to reproduce

• Add an incorrect character to the end of a seed peer ID, such as '\'.
• Run p2p microservice

Environment
