Source Trello: add support to sync data for entire organisation

[dakotamccarty]

I'm needing to do organisation wide backups of Trello data. Currently the source only allows for boards that the API key holding is a member of but this leaves out a lot of boards and it's not really realistic to have the API key holder join every board.

A perfect solution would be the ability to pass a parameter (checkbox in the UI?) to retrieve all boards from the organisation and not just the member.

I've used this repo to get the data https://github.com/jtpio/trello-full-backup. However, it'd be great to keep it all in Airbyte specifically.

I'm using Airbyte in Digital Ocean via the fancy create droplet button and am not 100% sure how to go about updating the Trello source (or making my own custom one) to allow for this. I do think I'd be able to update enough to get the issue fixed on my own otherwise.

It looks like a new feature request

For now, we get a list of Trello boards using the endpoint:

https://api.trello.com/1/members/me/boards

it allows getting a list of the boards that the user is a member of.

The customer wants to improve the connector and be able to fetch boards to which he is not a member but has access.
