Redhat7:Apache changes

https service control

Having moved away from sysV init scripts, admins should moveto using the aoachctl and systemctl command.

#new command
apachectl graceful

Private /tmp

For enhanced security the systemd unit runs the httpd daemon using a private /tmp directory, separate to the system /tmp.

Many of the default settings are now hard coded and no long defined in the configuration files.
