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 (feat: Supporting SOPS for helm. #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 .....

Workaround

A shell script like

#!/bin/sh
exec /usr/local/bin/helm secrets "$@"

can be placed in /usr/local/sbin/helm. Since ArgoCD calls helm, /usr/local/sbin/helm instead /usr/local/bin/helm will be executed since /usr/local/sbin/ is preferred over /usr/local/bin/´, because it has a higher priority in the PATH
