+- Added new configuration field named `LeaseDuration` for `EVM.NodePool` that will periodically check if internal subscriptions are connected to the "best" (as defined by the `SelectionMode`) node and switch to it if necessary. Setting this value to `0s` will disable this feature.

 - Simple password use in production builds is now disallowed - nodes with this configuration will not boot and will not pass config validation.
 - Helper migrations function for injecting env vars into goose migrations. This was done to inject chainID into evm chain id not null in specs migrations.
 - OCR2 jobs now support querying the state contract for configurations if it has been deployed. This can help on chains such as BSC which "manage" state bloat by arbitrarily deleting logs older than a certain date. In this case, if logs are missing we will query the contract directly and retrieve the latest config from chain state. Chainlink will perform no extra RPC calls unless the job spec has this feature explicitly enabled. On chains that require this, nops may see an increase in RPC calls. This can be enabled for OCR2 jobs by specifying `ConfigContractAddress` in the relay config TOML.
