simp-ssh module appends settings for specific hosts to the end of ssh_config
Description
Added settings to ssh_config for a specific host as described in https://simp.readthedocs.io/en/master/user_guide/HOWTO/Configure_Ssh.html#managing-client-settings-for-specific-hosts. The changes were incorporated into the ssh_config file, but the were added at the end. Because ssh stops at first match when reading ssh_config, it stop when it finds the parameter in `Host *` and the host specific settings are not read.
Acceptance Criteria
Activity
As explained at https://stackoverflow.com/questions/24049176/modifying-ssh-config-with-augtool, augeas parses the file looking for a match and appends to the end of the file if no match is found.
You could file an issue with the augeasproviders_ssh project asking that they expose the before keyword as illustrated in their wiki and in the stackoverflow answer.
