Skip error records option

Support option for skipping error records instead of aborting.
Error records should be written in log file (or another OutputPlugin?).
And user may want to know number of error records.

Start by reviewing the JDBC output plugin's current error-handling path and how its OutputPlugin integration works. Define the option behavior, error-record destination, and reporting of the error count from the issue requirements. Done means error records can be skipped, preserved in the selected output, and counted for the user.

Written by the indexing model from the issue text.
