Remove outdated zone migration documentation note

In a recent patch [1], a bug in the zone migration strategy was fixed,
which prevented audits using this strategy to create action plans
with both instance and volume migrations. We documented this limitation,
but forgot to remove the note when fixing this bug.

+Action Plans
+============
+
+An ``Action Plan`` specifies a flow of ``Actions`` that should be executed
+in order to satisfy a given ``Goal``. It also contains an estimated
+``global efficacy`` alongside a set of ``efficacy indicators``.
+
+An ``Action Plan`` is generated by Watcher when an ``Audit`` is successful
+which implies that the ``Strategy`` which was used has found a ``Solution``
+to achieve the ``Goal`` of this ``Audit``.
+
+In the default implementation of Watcher, an action plan is composed of
+a graph of linked ``Actions``. Each action may have parent actions, which
+should be executed prior to child action.

+=======
+Actions
+=======
+
+An ``Action`` is what enables Watcher to transform the current state of a
+``Cluster`` after an ``Audit``.
+
+An ``Action`` is an atomic task which changes the current state of a target
+Managed resource of the OpenStack ``Cluster`` such as:
+
+-  Live migration of an instance from one compute node to another compute
+   node with Nova
+-  Changing the power level of a compute node (ACPI level, ...)
+-  Changing the current state of a compute node (enable or disable) with Nova
+
+In most cases, an ``Action`` triggers some concrete commands on an existing
+OpenStack module (Nova, Neutron, Cinder, Ironic, etc.).
+
+An ``Action`` has a life-cycle and its current state may be one of the
+following:
+
+-  **PENDING** : the ``Action`` has not been executed yet by the
+   ``Watcher Applier``.
+-  **SKIPPED** : the ``Action`` will not be executed because a predefined
+   skipping condition is found by ``Watcher Applier`` or is explicitly
+   skipped by the ``Administrator``.
+-  **ONGOING** : the ``Action`` is currently being processed by the
+   ``Watcher Applier``.
+-  **SUCCEEDED** : the ``Action`` has been executed successfully
+-  **FAILED** : an error occurred while trying to execute the ``Action``.
+-  **DELETED** : the ``Action`` is still stored in the ``Watcher database``
+   but is not returned any more through the Watcher APIs.
+-  **CANCELLED** : the ``Action`` was in **PENDING** or **ONGOING** state and
+   was cancelled by the ``Administrator``
+
+``Actions`` are created by ``Watcher Planner`` as result of Audit's execution.
+``Action`` can't be created, modified or deleted by user.

+Audits
+======
+
+There are creating, listing, updating and deleting methods of Watcher Audit
+resources which are implemented via the ``/v1/audits`` resource.
+
+In the Watcher system, an ``Audit`` is a request for optimizing a ``Cluster``.
+
+The optimization is done in order to satisfy one ``Goal`` on a given
+``Cluster``.
+
+For each ``Audit``, the Watcher system generates an ``Action Plan``.
+
+Create Audit
+============
+
+.. rest_method::  POST /v1/audits
+
+Creates a new Audit resource.
+
+Mandatory attribute to be supplied: ``audit_type``.
+
+``Audit`` can be created either based on existed ``Audit Template`` or by
+itself. In the first case, there also should be supplied
+``audit_template_uuid``. If ``Audit`` is created without ``Audit Template``,
+``goal`` should be provided.

+Audit Templates
+===============
+
+There are creating, listing, updating and deleting methods of Watcher Audit
+Template resources which are implemented via the ``/v1/audit_templates``
+resource.
+
+An Audit may be launched several times with the same settings
+(Goal, thresholds, ...). Therefore it makes sense to save those settings in
+some sort of Audit preset object, which is known as an Audit Template.
+
+An Audit Template contains at least the Goal of the Audit.

+Goals
+=====
+
+A ``Goal`` is a human readable, observable and measurable end result having
+one objective to be achieved.
+
+Here are some examples of ``Goals``:
+
+-  minimize the energy consumption
+-  minimize the number of compute nodes (consolidation)
+-  balance the workload among compute nodes
+-  minimize the license cost (some software have a licensing model which is
+   based on the number of sockets or cores where the software is deployed)
+-  find the most appropriate moment for a planned maintenance on a
+   given group of host (which may be an entire availability zone):
+   power supply replacement, cooling system replacement, hardware
+   modification, ...

+Scoring Engines
+===============
+
+A ``Scoring Engine`` is an executable that has a well-defined input, a
+well-defined output, and performs a purely mathematical task. That is,
+the calculation does not depend on the environment in which it is running - it
+would produce the same result anywhere.
+
+Because there might be multiple algorithms used to build a particular data
+model (and therefore a scoring engine), the usage of scoring engine might
+vary. A metainfo field is supposed to contain any information which might
+be needed by the user of a given scoring engine.

+
+A ``Strategy`` is an algorithm implementation which is able to find a
+``Solution`` for a given ``Goal``. To get more information about strategies
+that are shipped along with Watcher, visit `strategies page`_.
+
+There may be several potential strategies which are able to achieve the same
+``Goal``. This is why it is possible to configure which specific ``Strategy``
+should be used for each goal.

+Some strategies may provide better optimization results but may take more time

+API versions
+============
+
+In order to bring new features to users over time, the Watcher API
+supports versioning. There are two kinds of versions in Watcher.
+
+- ''major versions'', which have dedicated URLs.
+- ''microversions'', which can be requested using the
+  ``OpenStack-API-Version`` header.
+
+.. note:: The maximum microversion depends on release.
+  Please reference:
+  `API Microversion History
+  <https://docs.openstack.org/watcher/latest/contributor/api_microversion_history.html>`__
+  for API microversion history details.
+
+The Version API resource works differently from other API resources as they *do not*
+require authentication.
+
+If Watcher receives a request with unsupported version, it responds with a 406 Not Acceptable,
+along with the -Min- and -Max- headers that it can support.
+
+List API versions
+=================
+
+.. rest_method::  GET /
+
+This fetches all the information about all known major API versions in the
