refactor: rename active validators to round validators

[sebastijankuzner]

Summary

Use new naming structure:

• Registered validators -> All validators that are registered including resigned validators
• Round validators -> Top N validators with the highest vote balance, that participate in the consensus
• Resigned validators -> Validators that resigned from the consensus
• Active validators -> Round validators that are not resigned and have a valid BLS public key
• Inactive validators -> Validators that are resigned or do not have a valid BLS public key

Checklist

• Tests (if necessary)
• Ready to be merged
