Context Data Scoping

[cdavernas]

What would you like to be added:

Add a feature to enable scoping $context data.

Why is this needed:

In some specific cases, a user might want to only provide a slice of its context data to sub tasks, which is especially true when performing iterations (for/while) to avoid useless bloating.

It is also true for parallel writes, which you'd rather have on a small slice of a potentially huge context than on its whole. Google Workflows addresses that by explicitly sharing variables.

I think that to properly discuss this we need a pointer to the current section of the doc where $context and variable scoping is discussed.

I opened dicussion #890. I think we need to discuss a few thing before considering this case.
