[docs] lambdas are now required for declaring hooks in config.py

[Alfredo Deza]

The current docs mention in the examples that you must use a lambda for hooks:

app = {
    'root' : '...'
    # ...
    'hooks': lambda: [SimpleHook()]
}

But that is *new* behavior, yet nothing mentions that. "New in version N.N.N" is what I would expect the least for backwards incompatible changes like this one.

[Ryan Petrello (ryan-petrello)]

You've got it backwards. The old behavior was a list of hooks. The new behavior is a lambda. We implemented it this way to prevent people from shooting themselves in the foot with circular dependencies. The current documentation reflects the "best practice".

Then this ticket needs to be rephrased to indicate properly that the lambda is *new in version N.N.N*
