Configuration for Debezium source connectors in production are typically large, ours are 60+ lines.

Current implementation logs each key/value pair separately, this is inefficient and can be hard to follow.

Current implementation is here

Proposed solution: log connector configs in one statement as is done for Kafka, e.g:

ConsumerConfig values: 
	allow.auto.create.topics = true
	auto.commit.interval.ms = 5000
	auto.include.jmx.reporter = true
	auto.offset.reset = earliest
	bootstrap.servers = []
	check.crcs = true
	client.dns.lookup = use_all_dns_ips
	client.id = 
	client.rack = 
	connections.max.idle.ms = 540000
	default.api.timeout.ms = 60000
	enable.auto.commit = false
	enable.metrics.push = true
	exclude.internal.topics = true

Proposed implementation: use StringBuilder in BaseSourceTask.start() to build an aggregated connector configuration log message and log in one statement.

Additional benefit: connector configuration logs ingested into DataDog are in one record.
