    Get a file from a container

    name :
        Name of the container

    src :
        The source file or directory

    dst :
        The destination file or directory

    mode :
        Set file mode to octal number

    uid :
        Set file uid (owner)

    gid :
        Set file gid (group)

    remote_addr :
        An URL to a remote Server, you also have to give cert and key if
        you provide remote_addr and its a TCP Address!

        Examples:
            https://myserver.lan:8443
            /var/lib/mysocket.sock

    cert :
        PEM Formatted SSL Certificate.

        Examples:
            ~/.config/lxc/client.crt

    key :
        PEM Formatted SSL Key.

        Examples:
            ~/.config/lxc/client.key

    verify_cert : True
        Wherever to verify the cert, this is by default True
        but in the most cases you want to set it off as LXD
        normaly uses self-signed certificates.

    # the decimal integer 600 (and not the octal 0600). So, it it's
