Target functionality for 1.0

[dshoreman]

This issue is a list of all features that should be present and functional to cover the most common tasks in setting up and running an nginx server with multiple live sites.

Server

• Create a user on the server (for non-root shell and things like bots or ZNC that run a binary)
• Add groups to a user (or users to a group - eg to add www-data)
• Configure firewall rules
• Nginx server configs
• Clone and pull site files from Git
• Create a database for a project
• Install npm/composer dependencies
• Migrate database (for Laravel/Symfony type projects)
• Restore database from a dump (to move an existing db)
• Set permissions on files or directories (possibly recursively)
• View status of and stop/start/restart services

Servidor-specific

• Add extra users
• Restrict features on a user or group basis
• Change name, email, password etc
• Set dark mode, editor preferences etc from one place

Nice to haves (maybe after 1.0)

• Ability to pick between Apache/Nginx, or MySQL/MariaDB/PostgreSQL etc
• Custom nginx config / server block snippets
• Edit site config files such as .env from site editor
