We don't need imp here.

> Tools/Scripts/webkitpy/benchmark_runner/browser_driver/__init__.py:15
> +import imp

Ditto.

> Tools/Scripts/webkitpy/benchmark_runner/browser_driver/__init__.py:23
> +        BrowserDriverFactory.add_product([browser_driver_class.platform, browser_driver_class.browser_name], browser_driver_class)

This code is unreadable. We should just not use GenericFactory.add_product here.
Just add add_browser_driver(platform, browser_name, browser_driver_class) or something to BrowserDriverFactory.

> Tools/Scripts/webkitpy/benchmark_runner/generic_factory.py:38
> +    @classmethod

> +        item = cls.products

> +        item[descriptions[-1]] = product

This method is super generic and impossible to reason about.
I'd much prefer duplicating the code in each driver factory instead.

> Tools/Scripts/webkitpy/benchmark_runner/utils.py:21
> +    if inspect.isclass(child):
> +        if parent_name in [cls.__name__ for cls in inspect.getmro(child)]:

This should be re-rewritten as:
return inspect.isclass(child) and parent_name in [cls.__name__ for cls in inspect.getmro(child)]

> Tools/Scripts/webkitpy/benchmark_runner/utils.py:26
> +        if filename.endswith('.py') and filename not in ['__init__.py']:

Instead of nesting if-s, use "continue" and detect the rest per WebKit coding style.
Alternatively, use list comprehension.

Should I add a add_benchmark_builder method instead?

> Tools/Scripts/webkitpy/benchmark_runner/http_server_driver/__init__.py:23
> +        HTTPServerDriverFactory.add_product([http_server_driver_class.name], http_server_driver_class)

Should I change here as well?

Nice!

I don't think we should rename this to `get`.
`create` is more semantically correct name.
