Pool's flush and flush-strategy configuration

[Stefano Maestri]

I have merged the initial version of the Pool's flush functionality and its flush-strategy configurtation.

What is changing from IJ 1.x is CM matching consider our Unified Security mechanism.

I have also added a lot of tests to get a good coverage and also to avoid as much as possible regression

Please have a look to the commit and give me your thoughts

Yeah, looks good.

I think the only question is really if we should keep the ManagedConnectionPool level policies and instead always flush on a pool level, as the management operation would.

There are pros/cons of each solution, so lets keep it as IronJacamar 1.x for now, unless somebody else thinks otherwise.
