Add Target Allocator/Stateful Set Option

[blakeromano]

The CRD for the collector allows for the creation of the target allocator for prometheus which uses some of the data from the config on the collector regarding prometheus. However the Helm Chart has not added that support as well. This should be done to add awareness and adoption of the Target Allocator especially since lots of work on the Prometheus/Opentelemetry work has been going on

@blakeromano thanks for the heads up.
In the current operator chart we don't create/manage any custom resources (like the OpentelemetryCollector), we just provide some examples in the readme in order for the user to create and manage his own collector/s
Can you clarify what is the expectation regarding the targetAllocator resource?

I am not suggesting that you have to use the CRD. The CRD happens to allow the option to start up a pod that uses the collector's prometheus configuration and spins up a pod to do that work. I'd like to see the Helm Chart also have that functionality. Maybe a new helm chart to combine to Collector and Operator into one helm chart?

@blakeromano is this issue related: #69

Related yes. I think there is a benefit to having a helm chart that would do both the operator and collector without the usage of the CRD.
