Ability to contribute actions to context menu of extension in extensions viewlet

[sandy081]

Exposed new menu location extension/context to contribute actions for an extension. Eg:

"menus": {
			"extension/context": [
				{
					"command": "extension.helloWorld",
					"group": "2_configure"
				}
			]
		}

extension id is passed as an argument to the registered command.

vscode.commands.registerCommand('extension.helloWorld', (extensionId) => {
		vscode.window.showInformationMessage(extensionId);
	});

You can use the when condition "when": "extensionStatus==installed" if you want to have the action only on installed extensions.
