Case insensitive Constraints via IgnoreCase annotation

[njr-11]

Option 1 for case insensitive Constraints:
Give the repository method author an @IgnoreCase annotation with which to indicate when a Constraint should be applied independent of case. Typically it will be known upfront that the database contains a mixture of case, and it will be more convenient to specify this information in a single place on the repository method signature rather than everywhere it is used (where there is also the risk of forgetting to do it in one place).

Example usage:

List<Book> booksTitled(@IgnoreCase Constraint<String> title);

found = library.booksTitled(Constraint.equalTo("Developing with Jakarta Data"));

We should choose between this PR or #1006 (or if someone thinks of another way) for case-insensitive constraints

Comparing those two options, I would stay with this one.

@gavinking, what do you think?

I think I would not introduce a new top-level construct in our API for something marginally-useful with perfectly reasonable alternative solutions (JDQL, Restrictions).
