PSERV-1561 - Reconnect when readonly error is received from redis in Limitr client

[okeefem3]

Description

Adding a reconnectOnError handler for ioredis client that will reconnect if an error is emitted from the client that includes READONLY in the message.
This is important for environments where auto failover is not enabled to minimize incidents in limitr use cases when a failover does occur with an elasticache cluster.

This mimics the behavior used in belgrano.
