Argo-cd: Way to set helm command

[james-callahan]

For various reasons its desirable to modify the way that ArgoCD invokes helm

• Having multiple helm2 versions available for different clusters
• Various helm plugins
• Helm secrets management (#3024)

Proposal

Introduce a per-application or per-project config field that specifies which executable to invoke when running (each version of?) helm.
There is already a binaryName field in HelmVer: if the user has specified this variable, then place it in there.

is there a way to do this without this feature?

I need to invoke helm with:

helm secrets upgrade --install .....
