Add BeforeContainerInitialized in FluentDockerTestBase ctor

[miketof]

derived ctor is called after the FluentDockerTestBase ctor so basically, the OnContainerInitialized can be used exchangeable with ctor of the inherited class. But if I want to do some operation before Build and Start - I can't. That's my proposition is to implement BeforeContainerInitialized() virtual method as the first line of FluentDockerTestBase ctor.

Thanks @miketof - I'll add it to my TODO list.

Thanks!
Mario :)

Hi @miketof I've added several methods to participate in before build and before start - including before dispose (on error or test tear down).

Cheers,
Mario :)
