This is just a plain stupid and simple out-of-band helper without
anything fancy. It uses plain ssh to power off / power cycle the
machine, does not support power on. It support power status using fping
to check if the host replies.

When a node is running KVM instances and that node is rebooted or
shutdown, the gnt-noded daemon is finished and leaves the KVM instances
running. Latter on in the shutdown process, all remaining processes
receive SIGTERM as usual, meaning that the KVM instances are all
terminated, without running a proper shutdown procedure inside the
guests.

When using Xen, the xendomains script will take care of gracefully
powering down the instances, but for KVM there is nothing like that.

This patch adds an script that sends the "system_powerdown" command to
all running instances, and it could be useful for people using KVM.

This patch is a response for issue #126

Dictionaries are hard to encode into query strings, therefore the
“/2/instances/[instance_name]/reinstall” resource is changed to accept
its parameters via the request body. The old query string parameters are
still accepted for backwards compatibility.

To allow clients to detect whether a server supports the new body
parameters, a new feature string is added to the “/2/features” resource.
Some people might not like this, but it reuses existing functionality.

The RAPI client and its unittests are updated.

While starting to implement this, I found a number of deficiencies:

- Drop regular expressions. As it turned out, only very few fields for
  instances used them, all of which can easily be turned into static
  field names.
- Use two separate calls with a request and response description each.
- Add forgotten list of fields to query request.
- Add value status for case where a field is not available for an item,
  e.g. NIC 3 for an instance with only one network interface.
- Add "timestamp" field type.
- Updated examples.
