[Users] 3.3 scratch or upgraded installation must use Apache proxy (https://bugzilla.redhat.com/905754)

Hi, I'm working on https://bugzilla.redhat.com/905754, trying to have Apache proxy in all 3.3 installations. I'm looking in the code and I've found a point where I'm in doubt about how to handle the case. The current engine-setup implementation perform some checks that change the behavior of the installer documented as: 1. Check whether the relevant httpd configuration files were changed, as it's an indication for the setup that the httpd application is being actively used, Therefore we may need to ask (dynamic change) the user whether to override this configuration. 2. Check if IPA is installed and drop port 80/443 support. What the script really do is setting OVERRIDE_HTTPD_CONFIG default to False in both cases and just for case 2 call also setHttpPortsToNonProxyDefault. About 1, if we can consider Apache "owned" by the engine we can drop any question to the user, else I think we need to ask what to do or abort the setup considering the configuration as unsupported. About 2, it seems that the best solution for that is to abort the setup if IPA is found on the same system where we're installing the engine. As far I've understood having IPA and engine on the same host is not a supported configuration. What do you think about this? -- Sandro Bonazzola Better technology. Faster innovation.
