Generic power interface for soft reboot and soft power off

This patch updates the generic power interface to support SOFT_REBOOT
and SOFT_POWER_OFF. And also it introduces "timeout" optional
parameter for all power operations.

REST API Version History
========================
**1.27** (Ocata)
Add ``soft rebooting`` and ``soft power off`` as possible values
for the ``target`` field of the power state change payload, and
also add ``timeout`` field to it.
**1.26** (Ocata)
Add portgroup ``mode`` and ``properties`` fields.

features:
- Support ``soft rebooting`` and ``soft power off`` requests to
change node's power state with API version 1.27, and also
introduce ``timeout`` optional parameter and
``[conductor]/soft_power_off_timeout`` configuration option.
Custom power drivers may be enhanced to support this feature.
