Subject: [PATCH] units: add remote-cryptsetup.target and
remote-cryptsetup-pre.target
The pair is similar to remote-fs.target and remote-fs-pre.target. Any
cryptsetup devices which require network shall be ordered after
remote-cryptsetup-pre.target and before remote-cryptsetup.target.
Cherry-picked from: 889128b8b27abb13e1691a72e4ce0562c564e257
Resolves: #1384014
