Parameter Hints for Function Calls

[Suraj-Yadav]

Is your feature request related to a problem? Please describe.
For function calls, sometimes it becomes quite difficult to tell what a argument actually does. Usually it happens when the arguments passed are boolean/integer. We can hover over the call and it would show the signature, but it would be helpful if we can tell this directly at a glance.

func log(message string, appendTime bool) {
	if appendTime {
		fmt.Print(message, "at", time.Now())
	} else {
		fmt.Print(message)
	}
}

log("Process Started", true)

log("Still Running", false)

Describe the solution you'd like
We can have something like Parameter hints in Webstorm.

Describe alternatives you've considered
The only alternative I see is hover.

You can enable placeholders to view the function signature inline using:

    "gopls": {
        "ui.completion.usePlaceholders": true
    }

Signature help with usePlaceholders=false:

Signature help with usePlaceholders=true:

This feature request sounds like its for inspecting the code, not for help filling in the values, correct?
