Support Apache2 Webserver and make it the default

[ypid]

The problem that I am trying to solve with this is a timeout of the remote.php script when syncing. I was able to reproduce the problem with nginx, switching to Apache2 fixed it. Not sure yet how this can be fixed for nginx. I will probably dig even more into this before going the Apache2 route.

• Check if PHP config can somehow be fixed/changed
• Check if nginx config can somehow be fixed/changed (Reverting to an old version seems to fix it, investigating) → Should work with Nginx but some issues could not be determined.
• Write debops.apache role → debops.apache
• Support Apache in this role – Add support for the Apache HTTP Server. Nginx is still the default. #64
• Update debops.owncloud to use the role by default

ownCloud as well as NextCloud only support Apache2 with mod_php officially (refs: ownCloud, NextCloud)

I guess I can close this. This was only implemented for compliance reasons. I think all issues I had back then were not caused by Nginx. But it is good of course to rule this out by running a fully supported setup. I am closing this issue because I have no plan to deploy neither ownCloud nor Apache for this role. The later one might make sense to keep for testing as explained.
