httpd.service failed to start with an error "Cannot assign requested address: AH00072: make_sock: could not bind to address" during system boot

Issue

httpd.service fails to start during system boot when both of the following cases are satisfied:
- httpd is configured to listen on a specific IP address in its configuration
- NetworkManager.service is disabled

The following messages can be seen when attempting to start the httpd service during system boot:

httpd: (99)Cannot assign requested address: AH00072: make_sock: could not bind to address 12.34.56.78:80
httpd: no listening sockets available, shutting down
httpd: AH00015: Unable to open logs
systemd: httpd.service: main process exited, code=exited, status=1/FAILURE
kill: kill: cannot find process ""
systemd: httpd.service: control process exited, code=exited status=1
systemd: Failed to start The Apache HTTP Server.
systemd: Unit httpd.service entered failed state.
systemd: httpd.service failed.

• During boot systemd executes httpd.service before the network is completely up and running, which causes httpd to fail. This was reported in Fedora 17 as Bug 921566 - httpd does not wait for network start and fails. When it is going to be fixed in RHEL7?

• Is there a fix available for https://bugzilla.redhat.com/show_bug.cgi?id=1352139 in RHEL7?

• The issue occurs with IPv6 and it is not fixed by the newer package than systemd-219-42.el7.
