Plugin Extensions: Custom limits for extensions-per-plugin

Preface

Until now we were always limiting the extensions per plugins to 2, regardless of the extension point. We figured that this is something that varies by what we are trying to extend, and it should be the extension point that decides how many extensions it allows from the same plugin.

What changed?

We are not limiting the number of extensions by default, and return all of them unless the extension point specifies a limit explicitly.

// No limit set  -> All extensions
const { extensions } = getPluginExtensions({
    extensionPointId: PluginExtensionPoints.DashboardPanelMenu,
    context: {},
});

// Limiting -> Only return the first 2 extensions for every plugin
const { extensions } = getPluginExtensions({
    extensionPointId: PluginExtensionPoints.DashboardPanelMenu,
    context: {},
    limitPerPlugin: 2,
});
