Place upper bound on python-dracclient version

The idrac hardware type requires python-dracclient versions greater than
or equal to 1.3.0 and less than 2.0.0.

This is not a backport of a similar change which merged on the master
and stable/stein branches [1]. That change specifies python-dracclient
versions greater than or equal to 1.5.0 and less than 3.0.0 are
required.

Subsequently, a change which merged only on master modified the bounds
to greater than or equal to 3.0.0 and less than 4.0.0 [2].

+iDRAC driver
+============
+
+Overview
+========
+
+iDRAC_ hardware is supported by the ``idrac`` hardware type. It is also
+supported by the standard ``ipmi`` hardware type, though with a smaller
+feature set.
+
+.. TODO(dtantsur): supported hardware
+
+Enabling
+========
+
+The ``idrac`` hardware type requires the ``python-dracclient`` library to be
+installed, for example::
+
+    sudo pip install 'python-dracclient>=1.3.0,<2.0.0'
+
+To enable the ``idrac`` hardware type, add the following to your
+``/etc/ironic/ironic.conf``:
+
+.. code-block:: ini
+
+    [DEFAULT]
+    enabled_hardware_types=idrac
+    enabled_management_interfaces=idrac
+    enabled_power_interfaces=idrac
+
+To enable all optional features (inspection, RAID and vendor passthru), use
+the following configuration:
+
+.. code-block:: ini
+
+    [DEFAULT]
+    enabled_hardware_types=idrac
+    enabled_inspect_interfaces=idrac
+    enabled_management_interfaces=idrac
+    enabled_power_interfaces=idrac
+    enabled_raid_interfaces=idrac
+    enabled_vendor_interfaces=idrac
+
+Enrolling
+=========
+
+The following command will enroll a bare metal node with the ``idrac``
+hardware type::
+
+    openstack baremetal node create --driver idrac \
+        --driver-info drac_address=http://drac.host \
+        --driver-info drac_username=user \
+        --driver-info drac_password=pa$$w0rd
+
+.. TODO(dtantsur): describe RAID support and inspection
+
+Known Issues
+============
+
+Nodes go into maintenance mode
+------------------------------
+
+After some period of time, nodes managed by the ``idrac`` hardware type may go
+into maintenance mode in Ironic.  This issue can be worked around by changing
+the Ironic power state poll interval to 70 seconds.  See
+``[conductor]sync_power_state_interval`` in ``/etc/ironic/ironic.conf``.
