Multiple Instances of Apache

[tiffanyfay]

Right now there needs to be a separate task for each instance of the Apache web server. Code can be refactored to allow multiple instances in one task if there is a demand for this. Commentary wanted.

I think it might be good idea, regarding that running multiple instances of Apache is officially recommended for some specific scenarios: https://wiki.apache.org/httpd/RunningMultipleApacheInstances

Also it is quite simple to implement, for example by adding IP and port into dynamic namespace entry:

/intel/apache/127.0.0.1:8080/BusyWorkers
