Investigate supporting arguments/parameters per operation

[thbishop-intuit]

Currently the Argo CloudOps manifest format allows for customizing arguments and parameters but does not allow for customizing arguments by workflow type (sync vs diff). This is an issue because there are several arguments that are only valid for one or the other. Environment variables also fit into this issue.

One workaround is to use separate manifests for sync and diff.

One alternative could be to support a way to specify arguments and parameters per action separate from common actions. Ideally this would allow for common args/params to be set as well as customizations per action separately to minimize yaml duplication
