dirsrv service fails to start when nsslapd-listenhost is configured

Description of problem:
In some environments network initialization takes a long time (slow DHCP, etc). When nsslapd-listenhost is configured, dirsrv systemd service fails to start, because it doesn't wait for the network to be available (see attached bootchart)
Only dirsrv.target waits for the network.service. To make it more confusing, dirsrv.target reports that it's active, though no instances of dirsrv have been started:
[root@rhel7ds ~]# systemctl status dirsrv.target

Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Configure nsslapd-listenhost to use external IP address.
2. Disable link on that interface (unplug cable or in case of libvirt VM: virsh domif-setlink $VM_NAME vnetX down)
3. Restart the machine
4. Enable link during the startup when Network Manager waits for the link (that's the tricky part).

This is your proposed fix, right? Could you please open an upstream ticket https://fedorahosted.org/389/newticket and attach this patch (preferably in the git format patch since it could have your name and comments!) to the ticket? I'll ack it there.
Thank you so much!

looks like I can't create tickets there:
>TICKET_CREATE privileges are required to perform this operation
I'm attaching patch here. Please replace NNNNN with the ticket number.

Agh... This is due to the SPAM on the trac, most accounts are closed... :( Could you ask Rich to enable back your account for the future use. In the meantime, I'm going to open an upstream ticket and attach your patch to it.

Build tested: 389-ds-base-220.127.116.11-8.el7.x86_64
During the startup dirsrv waits for network. If address is assigned before the
timeout, DS starts up successfully. Otherwise it (rightfully) refuses to start
since there is no address to bind.
Marking as VERIFIED.
