Add parameterized limit support to smart query finder methods - findTopN(int limit) - rather than static findTop5()

[mshannongit]

Feature description

At the moment, it seems the only way to supply a dynamic parameterized limit value is by using a customized @query

@query(value = "SELECT * FROM books b WHERE b.title LIKE :title LIMIT :limit)
List findBooks(String title, int limit);

It would be good if a dynamic limit value could be inferred based on method name

List findTopNBooksByTitle(String title, int limit);
