create logging subsystem with access via web interface

[sergey-vdovin]

as for now the logging subsystem is missing in the web interface
current recommendation is to dig into dockers in order to understand the problem

Were you thinking about just adding a logging.error() here:

kuwala/kuwala/core/backend/app/controller/data_source/postgres.py

Lines 60 to 68 in 5930c7f

	def test_connection(connection_parameters: ConnectionParameters) -> bool:
	try:
	connection = get_connection(connection_parameters=connection_parameters)
	connection.close()
	except psycopg2.OperationalError:
	return False
	return True

Or something else?
