Allow a JDBC Appender to truncate strings to match a table's metadata column length limit.
Some databases like MySQL can be configured to cause SQL INSERT statements to fail when data for a column exceeds the length of a column definition.
In the case of MySQL 8, this is the default configuration, and asking a DB admin to change this to accommodate an application is not reasonable.
This feature would add a new attribute on the JdbcAppender called truncateStrings which would do so. This would be set to true by default for a smooth initial impression.
