KAFKA-5899 Added Connect metrics for connectors
Added metrics for each connector using Kafkaâs existing `Metrics`
framework. Since this is the first of several changes to add several groups of
metrics, this change starts by adding a very simple `ConnectMetrics` object
that is owned by each worker and that makes it easy to define multiple groups
of metrics, called `ConnectMetricGroup` objects. Each metric group maps to a
JMX MBean, and each metric within the group maps to an MBean attribute.
Future PRs will build upon this simple pattern to add metrics for source
and sink tasks, workers, and worker rebalances.
