Update Spring Integration metrics support since Spring Integration
`4.3.6`+ no longer needs `spring-integration-jmx` enable
`MessageChannel`, `MessageHandler` and `MessageSource` metrics.

- Add `IntegrationManagementConfiguration` conditional auto-configuration
  to provide `@EnableIntegrationManagement` when JMX is `enabled` or there
  is no `IntegrationManagementConfigurer.MANAGEMENT_CONFIGURER_NAME` bean.
  By default this bean doesn't exist and you explicitly should declare it
  (e.g. via `@EnableIntegrationManagement`) if you would like to collect
  metrics. At the same time Spring Integration enables it when JMX
  management is present (that is a purpose of that new
  `IntegrationManagementConfiguration`)

- Change `SpringIntegrationMetricReader` to read metrics from the
  `IntegrationManagementConfigurer`, not `IntegrationMBeanExporter`

- Change `PublicMetricsAutoConfiguration` to register
  `IntegrationManagementConfigurer.MANAGEMENT_CONFIGURER_NAME` bean if
  not present. Since we are here in `actuator`, therefore we are
  interested in the metrics for SI as well.

- Since we don't need JMX for the metrics any more, remove SI-JMX
  dependency from the `spring-boot-starter-integration`.

- Remove `IntegrationManagementConfiguration` modification from the
  `integrationMbeanExporter()`, since that looks like mutation of an
  external object, when end-user would prefer their own options.
  Therefore we don't need `ObjectProvider<IntegrationManagementConfigurer>`, too

- Add missed `MessageSourceMetrics` gathering for the
  `SpringIntegrationMetricReader`

* pr/7723:
  Fix typo in Kafka sample
  Fix compatibility with Apache Kafka 0.10.1

* pr/7714:
  Polish

Update KafkaProperties since  Apache Kafka `0.10.1` changed the type
for the `ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG` from the
`Long` to `Integer`.

Kafka includes the following conversion logic:

    case LONG:
        if (value instanceof Integer)
            return ((Integer) value).longValue();
        if (value instanceof Long)
            return (Long) value;
        else if (value instanceof String)
            return Long.parseLong(trimmed);

So we remain compatible with both `0.10.0` and `0.10.1`
