[PATCH] docs: explicitly permit a "commonly known identity" with SoB

["Daniel P. Berrangé" <berrange@redhat.com>]

The docs for submitting a patch describe using your "Real Name" with
the Signed-off-by line. Although somewhat ambiguous, this has often
been interpreted to mean someone's legal name.

In recent times, there's been a general push back[1] against the notion
that use of Signed-off-by in a project automatically requires / implies
the use of legal ("real") names and greater awareness of the downsides.

Full discussion of the problems of such policies is beyond the scope of
this commit message, but at a high level they are liable to marginalize,
disadvantage, and potentially result in harm, to contributors.

TL;DR: there are compelling reasons for a person to choose distinct
identities in different contexts & a decision to override that choice
should not be taken lightly.

A number of key projects have responded to the issues raised by making
it clear that a contributor is free to determine the identity used in
SoB lines:

 * Linux has clarified[2] that they merely expect use of the
   contributor's "known identity", removing the previous explicit
   rejection of pseudonyms.

 * CNCF has clarified[3] that the real name is simply the identity
   the contributor chooses to use in the context of the community
   and does not have to be a legal name, nor birth name, nor appear
   on any government ID.

Since we have no intention of ever routinely checking any form of ID
documents for contributors[4], realistically we have no way of knowing
anything about the name they are using, except through chance, or
through the contributor volunteering the information. IOW, we almost
certainly already have people using pseudonyms for contributions.

This proposes to accept that reality and eliminate unnecessary friction,
by following Linux & the CNCF in merely asking that a contributors'
commonly known identity, of their choosing, be used with the SoB line.
