Move isSuspended from BakerPoolStatus to ActiveBakerPoolStatus.

[td202]

Purpose

Relates to: Concordium/concordium-node#1309
Depends on: Concordium/concordium-grpc-api#76

This is intended to address the correct presentation of the suspended status of a validator pool: a validator pool's suspended status should be based on the suspended status on the pool owner's account.

Changes

• Add abpsIsSuspended to ActiveBakerPoolStatus.
• Remove psIsSuspended from BakerPoolStatus. This change should not affect the JSON serialization of BakerPoolStatus.

Checklist

• My code follows the style of this project.
• The code compiles without warnings.
• I have performed a self-review of the changes.
• I have documented my code, in particular the intent of the
  hard-to-understand areas.
• (If necessary) I have updated the CHANGELOG.

The changes look good. @td202 Could you explain, how this fixes Concordium/concordium-node#1309, as it's not really clear to me.

The fix is mainly in the related node PR: https://github.com/Concordium/concordium-node/pull/1310/files
Essentially, we get the suspended status from the "active baker", i.e. the record on the account, rather than from the state in the current epoch committee.
