Recent versions of OpenSSH remove support of ssh-rsa key types and host
key algorithms from the default conection configuration. Set options to
enable them and provide a configuration option which can disable them if
required.
Include config option within ssh_config command output template. Default
remote_user value to set username value. Include existence check on
provided config value to ensure file is available. Update tests to
include coverage on all changes. Add new options to the docs.
As of `net-ssh` version 4.2.0, the key :paranoid has been deprecated in
favor of using :verify_host_key. This commit updates Vagrants ssh config
to use the new key, and deprecates the use of :paranoid.
since we merged multiple private keys, the :private_key_path item of
ssh_info now comes back as an array. the ssh-config command had not yet
been updated to handle this properly.
here we fix that oversight and add a few unit tests around the config
generation.
This change makes it so that SSH errors are shown, whereas QUIET hid
those as well. The main change to QUIET was to get rid of warnings,
not errors, so this fixes that.
