Added Clickhouse applier support.

Issues: CT-383

If using the dropcolumn filter during extraction, in conjunction with the Batch Applier (eg Replicating to Redshift, Hadoop, Vertica) writes would fail with a CSV mismatch error due to gaps in the THL Index.

However, for JDBC appliers, the gaps are required to ensure the correct column mapping

To handle the two different requirements, a new property has been added to the filter to control whether or not to leave the THL index untouched (the default) or to re-order the Index ID's

If applying to Batch targets, then the following property should be added to your configuration. The property is not required for JDBC targets.

--property=replicator.filter.dropcolumn.fillGaps=true
