breaking-change(configtest, scan): categorize error

[MaineK00n]

What did you implement:

When scanning servers together in the CIDR Range or when many servers are defined in config.toml, I wanted to classify servers that have been successfully "configtest" or "scan" and those that have not.

Type of change

• Breaking change (fix or feature that would cause existing functionality to not work as expected)

How Has This Been Tested?
