Some attribute-set have a documentation (doc:), but it was not displayed
in the RST / HTML version. Such field can be found in ethtool, netdev,
tcp_metrics and team YAML files.

Only the 'name' and 'attributes' fields from an 'attribute-set' section
were parsed. Now the content of the 'doc' field, if available, is added
as a new paragraph before listing each attribute. This is similar to
what is done when parsing the 'operations'.

Note: this patch can be applied without conflicts on top of net-next and
docs-next. To be honest, it is not clear to me who is responsible for
applying it :)
