Ability to query list of associations for a given node

[m3ki]

Currently, we have the ability to query each node individually for each group:

OpenZWave/1/node/38/association/2/

For which I get

{
    "Name": "Basic_Set",
    "Help": "",
    "MaxAssociations": 5,
    "Members": [
        "36.0",
        "37.0"
    ],
    "TimeStamp": 1604267957
}

I would like to have an ability to get a result like this OpenZWave/1/node/38/associations For which I get

{
	"Name": "All associations",
	"Groups": {
		"1": [
			"36.0",
			"37.0"
		],
		"2": [
			"36.0",
			"37.0"
		]
	},
	"TimeStamp": 1604267957
}
