In #701, we created the managedOverride metadata which allows a user to override which of virtual/override keywords are placed on a method:

<attr path="//method[@name='example']" name="managedOverride">override</attr>
<attr path="//method[@name='example']" name="managedOverride">virtual</attr>

However, sometimes the desired fix is "none of the above". For example, there may not be a method to override, however the class is sealed so virtual is not a valid option either. Both keywords must be omitted.

We should add support for a third none option:

<attr path="//method[@name='example']" name="managedOverride">none</attr>
