Insert for entities of same type within an aggregate get inserted using JDBC batch operations when possible.
Inserts are supported when no id needs to be generated by the database or if the Dialect supports generation of ids in batch operations.

Added the missing functionality that is found in the documentation of spring-data-jdbc, but was not present in the code as functionality. Users can not choose between various QueryLookupStrategies.

We now associate a boolean value with both operators as those operators are rendered using equals comparison in the actual SQL text.

This allows both Spring Data R2DBC and Spring Data JDBC to use the same annotation.
See spring-projects/spring-data-jdbc/issues/1041, spring-projects/spring-data-r2dbc/pull/720, spring-projects/spring-data-jdbc/pull/1158
In this case the usage of `StringBuilder` has no additional benefit, since it is not inside a loop where the JVM may have problems detecting String concatenation that can be optimized. The usage of "simple" String concatenation makes the code more readable and the code will be automatically optimised by the compiler.

Refactored the unit tests to include a negative case and to separate the different scenarios tested.
Removed the default LockMode from the Lock annotation.
I have the feeling that most users will assume an exclusive Lock when none is specified, but also don't want to request stronger locks than required.

Methods which use the derive query functionality now can be annotated with `@Lock` to used a given `LockMode`. Right now there are two different modes `PESSIMISTIC_READ` and `PESSIMISTIC_WRITE`. Based on the dialect the right select is generated. For example for HSQLDB `Select ... FOR UPDATE`.

Rename "null handling" to "null precedence".
This is somewhat inconsistent with commons null handling, but more descriptive.
Minor formatting.

java.sql.Types constants are int values and therefore make it tedious to read and debug the code.
SQLType values are mostly enum constants which are much nicer to use.

This is achieved by passing the full availabe type information of the conversion target to the conversion service.
This broke a test which wasn't functional in the first place which becomes obvious when adding the proper assertion.
