CIP: Ginger (v3) Network Upgrade

This is for discussing the v3 upgrade, which I propose we call the “Ginger Peppermint Network Upgrade.”

The Ginger Peppermint upgrade should be a Meta CIP, which includes:

• CIP-21: Introduce blob type with verified signer
• CIP-24: Versioned Gas Scheduler Variables
• CIP: Limit number of PFBs and non-PFBs per block, increase transaction size limit
• CIP: Decrease block time to 6 seconds

Planning to update this to “Cinnamon Ginger Network Upgrade” from a suggestion by @ninabarbakadze

This will also include a CIP, which I prepare to draft this week: CIP: Decrease block time to 6 seconds

And also CIP: Limit number of PFBs and non-PFBs per block, increase transaction size limit
