fix: Ability to add custom toolbar items to main page nav bar

[phantomjinx]

This is an attempt to address the dynamic navbar that displays in hawtio-online. The toolbar dropdown is dynamic in that it changes link target, dependent on which plugin route is active. Therefore, this solution attempts to mirror this functionality.

To test, execute yarn start and click on Example 3 plugin to see the newly added custom toolbar items for that plugin.

---

• core.ts

  • Adds optional toolbarItems property to plugin interface

• HawtioHeader.tsx

  • Picks up the plugins from the context and find the plugin that is currently being displayed. If this plugin has a toolbar item property then pick up the components into a custom toolbar group

Also, please update the description of the Example 3 page body to explain what this example demonstrates (i.e. extending the header with custom actions).

Also, this should be feat: instead of fix: as it brings a new feature.
