Update jaeger README to use correct parameters (helm#4445)

* Update jaeger README to use correct parameters

This fixes two separate doc bugs:
1. When using the elasticsearch storage backend,
   `storage.type=elasticsearch` must be set. The given example
   didn't include this param.
2. The param names for the query service didn't match the ones in the code.

 ```bash
-$ helm install incubator/jaeger --name myrel --set provisionDataStore.cassandra=false  --set provisionDataStore.elasticsearch=true

 After a few minutes, you should see 2 ElasticSearch client nodes, 2 ElasticSearch data nodes, 3 ElasticSearch master nodes, a Jaeger DaemonSet, a Jaeger Collector, and a Jaeger Query (UI) pod deployed into your Kubernetes cluster.
