Add support for SQLite

[rudolfschmidt]

I would like to use and test data JDBC but for local development I use SQLite, and before I used spring data JPA that has a support by Hibernate but hibernate use a custom dialect implementation that is not compatible with spring data JDBC so my question is why is a famous database technology like SQLite not supported by Spring?

I am open to implement a dialect and make a pull request to contribute to the development but before doing so I would like to ask if there is already work going on in this direction?

We don't have the capacity to support more databases.
Please consider hosting the dialect in a separate repository.

We hope to eventually provide support for testing new dialects.
