Subject: Configure SELinux for httpd during upgrades

SELinux configuration for httpd instance was set for new
installations only. Upgraded IPA servers (namely 2.1.x -> 2.2.x
upgrade) missed the configuration. This lead to AVCs when httpd
tries to contact ipa_memcached and user not being able to log in.

This patch updates ipa-upgradeconfig to configure SELinux
in the same way as ipa-server-install does.
