Add Ocata (1.0.0) release notes

We publish our docs on ReadTheDocs (RTD). We also want to use "reno"
as release notes tools. Reno has issues to determine the repo root
when it gets used in an RTD build (see bug 1661319).
The bug is solved in reno>2.0.3 but that will be released *after*
the Ocata release. This means we need an interim solution to have
release notes ready at the same time when the actual release is
happening. This change is this interim solution.

+Release Notes

+
+1.0.0
+=====
+
+*nova-dpm* 1.0.0 is the first release of the Nova virtualization
+driver for the PR/SM hypervisor of IBM z Systems and IBM LinuxOne
+machines that are in the DPM (Dynamic Partition Manager)
+administrative mode.
+
+New Features
+------------
+
+* Configure a compute node to manage and consume only
+  a subset of a *z Systems* CPC in DPM mode.
+* CPC subsetting is hidden from users and they are treated
+  like normal hosts in OpenStack.
+* Spawn instance from FCP volume.
+* Instance lifecycle management.
+* Use flat networking.
+
+Known Issues
+------------
+
+* VLAN and tunneled networks are not supported in this release.
+* Cinder driver for Storwize V7000 Unified returns additional WWPN's
+  which are tagged as NAS, which are used for internal connections.
+  The invalid target WWPN's need to be blacklisted in nova
+  configuration parameters.
+* Fibre Channel Multipathing is not supported.
+* The configuration parameter ``[DEFAULT].host`` cannot be more than
+  17 characters in length.
+* Networking: 12 ports per partition at the maximum.
+* Networking: In the guest image, always port 0 of an network adapter gets
+  autoconfigured. If port 1 should be used, manually deconfigure port 0 and
+  configure port 1 in the operating system of the launched instance.
+* Boot from image is not available. Boot from volume has to be used.
+* Only a single fibre channel network is supported. Configured storage
+  adapters and cinder fibre channel backends must all use the same fibre
+  channel network.
+* The configured maximum number of partitions (``[dpm].max_instances``)
+  is not yet enforced.
+* All bug reports are listed at: https://bugs.launchpad.net/nova-dpm
