Allow custom links in the sidebar

[dantownsend]

Discussed in https://github.com/piccolo-orm/piccolo_admin/discussions/306

We can add a new section in the sidebar containing user defined links:

The API would be pretty simple:

app = create_admin(
    ...,
    sidebar_links=[
        ('Charts', '/custom-endpoint'),
        ('Top Movies', '/#/movie?__order=-box_office'),
        ...
    ]
)

It's useful for many reasons:

• In the Top Movies example, we're providing a quick way to get to certain pages with filters / sorting pre-applied.
• In the Charts example, this is if someone has added a custom page that they want to link to.

Considerations:

• Do we call it links or shortcuts?

I think 'shortcuts' is more descriptive.

I suppose that the sidebar links will be visible to only the admin users and not show up at all in the swagger docs?

@Fidel-C Piccolo Admin is protected by session auth and only the authenticated admin user can see the admin interface and admin Swagger docs. Want to do PR for this? If not, I can make a working prototype.

@sinisaos alright thanks for the answer.

@Fidel-C No problem. You didn't say anything about whether you will do PR or not? Do you want me to do initial PR?

Sorry about that. I think you should.

@Fidel-C PR #308, so you can try it if you want.

@dantownsend You can close this because it's done.
