hibernate-resume: add a tool to write a device node's major:minor to /sys/power/resume.
This can be used to initiate a resume from hibernation by path to a swap device containing the hibernation image. The respective templated unit is also added. It is instantiated using path to the desired resume device.

+ <title>Description</title>
+
+ <para><filename>systemd-hibernate-resume@.service</filename> is a
+ service that initiates hibernation resume from a device
+ containing the resume image. It is instantiated for each
+ device that is configured for resuming from.</para>
+
+ <para><filename>systemd-hibernate-resume</filename> only supports
+ the in-kernel hibernation implementation, known as swsusp.
+ Internally, it works by writing the major:minor of specified
+ device node to <filename>/sys/power/resume</filename>.</para>
+
+ <para>Failing to initiate a resume is not an error condition.
+ It may mean that there was no resume image (e. g. if the
+ system has been simply powered off and not hibernated). In
+ such case, the boot is ordinarily continued.</para>
