> Add support of INSERT queries in PXF JDBC plugin:
>  * Implement `WriteAccessor` and `WriteResolver` interfaces. Both are implemented in the same classes as `ReadAccessor` and `ReadResolver`;
>  * Support query batching in Accessor. The size of a batch is defined by user and may be "infinite";
>  * In Accessor, use `java.sql.PreparedStatement` and built-in functions in it to process queries;
>  * In `setFields()` method of Resolver, perform type conversions of the data tuples received from PXF.
> Optimize and refactor the code in PXF JDBC plugin, make some fixes:
>  * Make functions for building WHERE statements static where possible to reduce the number of InputData checks;
>  * Organize imports;
>  * Check the codestyle;
>  * Fix the handling of TIMESTAMP values when performing SELECT requests.
> Improve documentation:
>  * Correct or rewrite Javadoc strings for plugin functions;
>  * Rewrite README.md.
