notify Service['sshd_service'] when file resource in config_file_server class changes

[absld]

Hi,

in class ssh::server, there is a subscribe from service {'sshd_service': } resource declaration to File['sshd_config'] resource, which causes the sshd service to be restarted after changes in sshd_config file.

Instead of defining our sshd settings within sshd_config file, we use the Include mechanism in combination with defining our custom sshd settings via ssh::server::config_files hash. This results in the configuration parameters get written into /etc/ssh/sshd_config.d/somefile. So far so good.

Unfortunately, there is no notify in the file resource within ssh::config_file_server class, which is declared in ssh::server class for each $config_files hash key. So, if configuration parameters change in /etc/ssh/sshd_config.d/somefile, the sshd service is not refreshed or restarted
