Horizon v0.16.0

Upgrade notes

• Ledger > Admins need to reingest old ledgers because we introduced successful_transaction_count and failed_transaction_count.

Database migration notes

Previous versions work fine with Horizon 0.16.0 schema so you can migrate (horizon db migrate up) database without stopping the Horizon process. To reingest ledgers run horizon db reingest using Horizon 0.16.0 binary.
