Horizon v2.11.0

Changes

• Add a new horizon flag --max-assets-per-path-request (15 by default) that sets the number of assets to consider for strict-send and strict-recieve requests (4046)
• Add an endpoint /liquidity_pools?account={account_id} which returns the liquidity pools an account is participating in 4043
• Add a new horizon command horizon db fill-gaps which fills any gaps in history in the horizon db. The command takes optional start and end ledger parameters. If the start and end ledger is provided then horizon will only fill the gaps found within the given ledger range 4060
• Improve performance of /liquidity_pools/{liquidity_pool_id}/effects endpoint by optimizing the db query to fetch effects for a liquidity pool 4065
• Include the captive core binary in the stellar/horizon Docker image 4019
• Remove --captive-core-reuse-storage-dir horizon flag 4048
• Improve performance of XDR encoding which should also improve ingestion speeds 4063, 4056, 3957
• Improve detection of when the Stellar Core binary has been modified 4050
• horizon_ingest_state_verify_ledger_entries metric was changed to gauge 4054
