Apache 2.4 support

[svanzoest]

@wayne530 We are working on Apache 2.4 support in the COOK-3900 branch. OneHealth has been running this in production for over 6 months, but we need to test it on other platforms and add a modern test suite before we know for certain it will work for everyone. You are welcome to give that branch a shot and provide us with feedback. We would appreciate it and it would help us get it out sooner.

@svanzoest Thanks - I am testing the COOK-3900 branch and it works well in Ubuntu 14.04 (so far). The only missing thing is a new parameter node.apache.version that is not documented, which controls some of the templates that will be used. Perhaps it can be inferred from the actual installed package/source? Anyway, thanks for the pointer and I'll let you know if we encounter any issues.

@wayne530 The parameter is described in the README. It is very tricky to determine the version from the package as it may not even be installed yet during the first run. So we currently require the user to specify the version explicitly. If we can improve that we will, but it is sort of a chicken and egg problem and we have no easy way of knowing which version package will install.

@svanzoest Thanks - I did find the doc reference. The way it works with most other cookbooks, and perhaps that is not a possibility here, is that the version param also drives the version of the package or source that is installed. In that way, there will not be an inconsistency between the installed package/source and the setting. I would expect setting it to 2.4 in an environment where there is no 2.4 package to result in an error. Here the parameter only drives template/recipe-specific changes. Anyway, just a thought for a possible enhancement. Thanks for your help!

@wayne530 agreed. In cases where we can make an educated guess as to what the likely version of the package will be we can do that. There is no way we can guarantee that for all circumstances.
