Updated log4j version and configuration to guarantee a zero-day remote code exploit published for log4j cannot be used against Teku nodes.

Upcoming Breaking Changes

Support for the Pyrmont testnet will be removed in an upcoming release. The Prater testnet should be used instead.
The /teku/v1/beacon/states/:state_id endpoint has been deprecated in favor of the standard API /eth/v1/debug/beacon/states/:state_id which now returns the state as SSZ when the Accept: application/octet-stream header is specified on the request.
The /eth/v1/debug/beacon/states/:state_id endpoint has been deprecated in favor of the v2 Altair endpoint /eth/v2/debug/beacon/states/:state_id
The /eth/v1/beacon/blocks/:block_id endpoint has been deprecated in favor of the v2 Altair endpoint /eth/v2/beacon/blocks/:block_id
The /eth/v1/validator/blocks/:slot endpoint has been deprecated in favor of the v2 Altair endpoint /eth/v2/validator/blocks/:slot
The commandline option --validators-performance-tracking-enabled has been deprecated in favour of --validators-performance-tracking-mode
The commandline option --network of the validator-client subcommand introduces a new option value auto, which automatically
fetches network configuration information from the configured beacon node endpoint. Other --network option values for an external validator client
are now deprecated in favour of this option value (usage: teku validator-client --network=auto)
