(feature) Allow cli tool to use retriever other than fileretriever #3876
Description
Requirements
Currently pkg/cli tool is capable only to use local file while performing evaluation of flag(s). This is hardcoded as follows
func (e evaluate) Evaluate() (map[string]model.RawVarResult, error) {
c := ffclient.Config{
PollingInterval: 10 * time.Minute,
DisableNotifierOnInit: true,
Context: context.Background(),
Retriever: &fileretriever.Retriever{Path: e.config},
FileFormat: e.fileFormat,
}I propose to expand the capability of this tool to support at least httpretriever. Ideally I think we should support each retriever.
