Add sync profile / schema creation promt

[MalteJanz]

a new CLI command to create a profile where the user is asked some questions:

• Which base entity (ideally with autocomplete / validation)
• Mappings
  • How is the CSV column called
  • What entity path (ideally with autocomplete / validation) should it match to

Scripting can be left out by this and later written in the file by the user himself.

Ideally we should use a library for promting, like https://crates.io/crates/inquire
