Page title + favicon in API pages

[sdktr]

NetBox version

v3.0-beta1

Feature type

Change to existing functionality

Proposed functionality

Add a favicon to both GraphiQL workspace and REST API. Plus add a page title to the GraphiQL playground.

Use case

When testing Netbox API calls the tabs in a browser do not stand out very recognizable. The page title for the REST API pages reflects the path one is on. The GraphiQL playground has no title so it renders the full query URL in the tab title.

@sdktr want to try taking this on? I'm not really sure how involved it would be.

[jeremystretch]

While we're at it we should see if it's feasible to serve the GraphiQL UI's static resources locally (as opposed to via a CDN), to better support isolated NetBox deployments.

@jeremystretch - I'm not sure there is a clean solution for that other than creating a pull request for graphene-django or forking it. Maybe it's possible to overwrite the path to the template and having a local version with the changes (local resources, favicon and title).

https://github.com/graphql-python/graphene-django/blob/e7f7d8da07ba1020f9916153f17e97b0ec037712/graphene_django/views.py#L58

But from my quick look any solution (including the above) would require monkey patching which seems like a bad idea.

[jeremystretch]

We're already subclassing the stock GraphQLView, so it should be pretty easy to swap in our own template. The template actually looks pretty minimal; should be easy to tweak. We just need to ensure we keep resources in sync for future releases; that will be the more tricky part.

Ok, I've got the title and favicon sorted in #6847, and we should be able to bundle the necessary static resources using our existing workflow. Just need to sync with @thatmattlove to confirm.
