EPIC: Partial Set Security

[mpoke]

Problem

This is a meta issue to track the work on opt-in security. With opt in security, validators will be able to decide which consumer chains they would like to validate on, and will only receive rewards for those that they are active on.

EDIT: Renamed to Partial Set Security. See this doc for a high level design.

Closing criteria

Partial Set Security is implemented.

Putting this work on hold as the following tasks are very likely needed to enable opt-in security:

• cryptographic equivocation EPIC: Cryptographic verification of equivocation #732
• redesigning ICS as a read-only protocol EPIC: Read-only protocol #1293
