KAFKA-5990: Enable generation of metrics docs for Connect
A new mechanism was added recently to the Metrics framework to make it
easier to generate the documentation. It uses a registry with a
MetricsNameTemplate for each metric, and then those templates are used when
creating the actual metrics. The metrics framework provides utilities that can
generate the HTML documentation from the registry of templates.
This change moves the recently-added Connect metrics over to use these
templates and to then generate the metric documentation for Connect.
This PR is based upon #3975 and can be rebased once that has been merged.

KAFKA-5902 Added sink task metrics

KAFKA-5902 Changed to measuring task processing lag behind consumer
Changed the `sink-record-lag-max` metric to be the maximum lag in terms of
number of records that the sink task is behind the consumer's position for any
topic partitions. This is not ideal, since often âlagâ is defined to
represent how far behind the task (or consumer) is relative to the end of the
topic partition. However, the most recent offset for the topic partition is not
easy to access in Connect.
