Add support for customizable transaction isolation level settings [JDBC]

See original GitHub issue

In some situations it would be useful to have the ability to override the default transaction isolation level when setting up the JdbcTemplateLockProvider.

Specifically it looks like an extension could be made to the JdbcTemplateLockProvider.Configuration class so that the desired isolation level could then be passed into the JdbcTemplateStorageAccessor for use by the transactionTemplate in the constructor. As it is currently implemented, I’m not sure how to do this via overrides since JdbcTemplateStorageAccessor is not public.

Well, specifically with the default isolation level there are errors showing up in the database logs regarding transactions needing to be restarted due to all of the running instances waking up vying to run the job. I’ve noticed that if I elevate isolation to SERIALIZABLE, these errors go away. However, I don’t want to use SERIALIZABLE on all of my connections, so having this as a customizable feature just for Shedlock solves the problem for me.
