implement nodeAddressMap for sentinel

[elimelt]

Description

Describe your pull request here

Adds support for nodeAddressMap to sentinel client options, equivalent to cluster's nodeAddressMap feature.

I'd like to be able to use/test Sentinel from outside a k8s cluster, but returned addresses aren't resolvable to the client

Closes https://github.com/redis/node-redis/issues/3144
