Allow Sidekiq shard configuration in omnibus and charts
To deploy .com with Sidekiq sharding, we need to allow the new routing rule formats on both deployment modes
- charts, so that k8s-workloads/gitlab-com can be updated
- omnibus-gitlab, so that the deployer nodes can be updated
While the Sidekiq shard router is behind a feature flag, we still need omnibus and charts to permit the new routing rule format which defines the name of the Redis instance for the route.
