Start a document explaining who administers/owns Fatiando accounts

[leouieda]

We have several accounts on different sites that are related to Fatiando. We need to create a list of who is an owner/administrator on each so we have a sense of what is going on and where we should add new maintainers. This would be good as a section of the README of this repository or a separate file.

Off the top of my head:

• Twitter
• fatiando.org domain (from Hover)
• GitHub organisation
• PyPI packages
• TestPyPI packages
• YouTube (Google brand account)

This should be written down in a document here. Either a separate file or in the MAINTENANCE.md file.

I like this idea. I would add a small list of minimum security measurements that each owner/administrator should follow:

• Strong password, only used in a single place, randomly generated.
• 2FA whenever possible.
• Not sharing personal credentials.
• Use of password manager is encouraged.

I know we cannot enforce these measurements, but having them written down it's better than taking for granted that every owner/administrator will apply them from the start.
