[Section Number and Name] 
Configuring CPU and memory requests for the log store

[Describe the issue] 
The example is having different values for limits.memory and request.memory and the values should be the same.

This is the example:

~~~
      elasticsearch:
        resources: 
          limits:
            memory: 16Gi
          requests:
            cpu: "1"
            memory: "64Gi"
~~~

And it should be like this:
~~~
      elasticsearch:
        resources: 
          limits:
            memory: 16Gi
          requests:
            cpu: "1"
            memory: 16Gi
~~~

or

~~~
      elasticsearch:
        resources: 
          limits:
            memory: 64Gi
          requests:
            cpu: "1"
            memory: 64Gi
~~~

At the same time, not only the value, the request.memory has the value between " " and the limits.memory not. Then, not consistency in the example. It's ok without " "
