Improve rendering of config arrays in logs

[yruslan]

Background

Pramen logs the incoming config in order to make investigating issues easier.

However, Pramen configs have many arrays (pramen.sources, pramen.sinks, etc).

And these arrays are not properly rendered, and secrets are not properly redacted.

pramen.sources = [{factory={class=za.co.absa.pramen.core.source.SparkSource}, name=csv, format=csv, has={information=
{date={column=false}}}, option={delimiter=,, header=true}}, notification.targets=["a", "b", "c"], {factory={class=za.co.absa.pramen.core.source.JdbcSource}, 
correct={decimals={in={schema=true}}}, name=postgre, save={timestamps={as={dates=true}}}, jdbc={password=test, 
driver=org.postgresql.Driver, connection={primary={url=jdbc:postgresql://test/db}}, user=test_user}, information={date={app=
{format=yyyy-MM-dd}, column=info_date, type=date, sql={format=YYYY-MM-DD}}}, has={information={date={column=true}}}, 
option={fetchsize=50000, batchsize=50000}},

Feature

Improve the rendering of arrays and make one log line per primitive value, or per array of primitive values.

Example

pramen.sources[0].factory.class="za.co.absa.pramen.core.source.SparkSource"
pramen.sources[0].name="csv"
pramen.sources[0].format="csv"
pramen.sources[0].notification.targets=["a"  "b"  "c"]
...
pramen.sources[1].jdbc.password=[ redacted ]
...
