cmd/k8s-operator: allow specifying replicas for connectors (#16721)

Browse Source 
This commit adds a `replicas` field to the `Connector` custom resource that
allows users to specify the number of desired replicas deployed for their
connectors.

This allows users to deploy exit nodes, subnet routers and app connectors
in a highly available fashion.

Fixes #14020
