Merge branch 'ia/ssh/public_keys/OTP-9911' into maint
* ia/ssh/public_keys/OTP-9911:
Correct access flag handling in sftpd
Client fallbacks to ipv4 if connection is refused with ipv6
Cleaned up code so that ssh_file can become a template for a documented ssh_keys behavior
Test case maintenance
Better handling of IPv6
Ssh daemon handles RSA host keys
Removed no longer needed code
Use the public_key application for all public key handling
