Documentation: Add inclusive-language documentation.

A recent series of commits to OVN made some changes to the language
used in code, comments, and documentation to be more inclusive. This
constitutes a follow-up that clarifies in the documentation what the
policy is and where the list of words to avoid can be found.

When starting this task, I found a commit to OVS [1] written by Simon
Horman that added basically everything I wanted to say. With Simon's
permission, I have copied the contents of that commit, changing all
instances of "Open vSwitch" to "OVN". Simon is credited as a co-author
on this commit.

+Inclusive Language
+==================
+
+In order to help facilitate an inclusive environment in the OVN
+community we recognise the role of language in framing our
+communication with each other. It is important that terms that
+may exclude people through racial, cultural or other bias, are avoided
+as they may make people feel excluded.
+
+We recognise that this is subjective, and to some extent is a journey.
+But we also recognise that we cannot begin that journey without taking
+positive action. To this end OVN is adopting the practice of an
+inclusive word list, which helps to guide the use of language within
+the project.

+
+Word List
+---------
+
+The intent of this document is to formally document the acceptance of a
+inclusive word list by OVN.  Accordingly, this document specifies
+use of the use the `Inclusive Naming Word List
+<https://inclusivenaming.org/word-lists/>`__ v1.0 (the word list) for
+OVN.
+
+The adoption of the word list intended that this act as a guide for
+developers creating patches to the OVN repository, including both
+source code and documentation. And to aid maintainers in their role of
+shepherding changes into the repository.
+
+Further steps to align usage of language in OVN, including clarification
+of application of the word list, to new and existing work, may follow.
