CLI : import from XML format

[vespian]

The CLI has an export option:

$ keepassxc-cli extract
Usage: keepassxc-cli extract [options] database
Extract and print the content of a database.

Options:
  -k, --key-file <path>  Key file of the database.

Arguments:
  database               Path of the database to extract.

but no import <!> Once the database is in XML format, I do not see a way to import it back :( What is more, the export option asks for password on STDOUT and prints database on STDOUT as well. This makes redirecting the output difficult.

Expected Behavior

It would be great if:

• there was an XML import option, both CLI and UI is fine
• the export command had an option to name the file to which the export should be done.

@vespian we already have an issue for the password prompt being displayed to stdout.

I remember someone proposing an import command for the CLI, but it was never implemented. Importing from the same xml format that we export to would make sense.

An option for a Yubikey would also be nice. cf #2451

This was implemented by #3572
