Describe the bug
[stable/prometheus] Failed to pass the flag storage.local.target-heap-size to prometheus

I add the flag storage.local.target-heap-size in configuration file to limit the memory usage, but it failed to start the POD.

server:
    extraArgs: 
        storage.local.target-heap-size: 10GiB

Version of Helm and Kubernetes:
Client: &version.Version{SemVer:"v2.12.3", GitCommit:"eecf22f77df5f65c823aacd2dbd30ae6c65f186e", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.12.3", GitCommit:"eecf22f77df5f65c823aacd2dbd30ae6c65f186e", GitTreeState:"clean"}

Client Version: version.Info{Major:"1", Minor:"14", GitVersion:"v1.14.0", GitCommit:"641856db18352033a0d96dbc99153fa3b27298e5", GitTreeState:"clean", BuildDate:"2019-03-25T15:53:57Z", GoVersion:"go1.12.1", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"13", GitVersion:"v1.13.12", GitCommit:"a8b52209ee172232b6db7a6e0ce2adc77458829f", GitTreeState:"clean", BuildDate:"2019-10-15T12:04:30Z", GoVersion:"go1.11.13", Compiler:"gc", Platform:"linux/amd64"}

Which chart:
[stable/prometheus]

What happened:
Failed to start the POD prometheues, I checked the log ,it said that the flag is invalid.

kubectl -n test-services log -c prometheus-server prometheus-server-6fdcc66945-n252m
Error parsing commandline arguments: unknown long flag '--storage.local.target-heap-size'
prometheus: error: unknown long flag '--storage.local.target-heap-size'

What you expected to happen:
the flag should be used to start prometheus server.

How to reproduce it (as minimally and precisely as possible):
helm install --namespace shared-services --name my-release -f prometheus.yaml stable/prometheus

prometheus.yaml can be found here.

Anything else we need to know:

[jinlxz]

The flag storage.local.target-heap-size is not supported since release version 2.0.

@jinlxz En, yes, after your reply, we know that it's not supported. But what we should use instead?
Can you help point out.

[jinlxz]

AFAIK, there is NO alternative to the flag.
