prohibit to call getDriver() as a static class member

[vdelendik]

we should identify that CarinaListener is loaded or not and allow to use IDriverPool methods only after this.
The most common problem is declaring driver = getDriver() as static class member which is executed on compilation phase when carina is not loaded yet.
as result we ignore all kind of properties etc. let's find a way to raise explicit business exception in case of any attempt to reuse IDriverPool in such way
