Now kdump.service runs "After" network.target. But network.target
doesn't mean network is setup and online[1]. We should use
network-online.target instead for ssh/nfs dump.
And also because nfs dump requires a mounted nfs when rebuilding kdump
initrd, kdump.service should also run "After" remote-fs.target (this
means all remote fs configured in /etc/fstab is mounted).
The downside of this patch is we always need to wait for network-online.target
even when dump target is a local disk. If network fails to come up,
kdump.service have to be stuck until network-online.target timeout (90
seconds by default).
