Add (simple) installation method

Is your feature request related to a problem? Please describe.
Currently, we are implementing a /install endpoint to configure DB settings.

Several errors are arisen when you use it:

• You can't define your admin user and password
• The HTTP server needs write permission in the root folder (highly insecure)
• The DB is seed

Describe the solution you'd like
A probind:install command that allows you to specify the settings.

Describe alternatives you've considered
