Fixed multi input prompt for MapReduceChain (#4979)
# Fixed multi input prompt for MapReduceChain

Added `kwargs` support for inner chains of `MapReduceChain` via
`from_params` method
Currently the `from_method` method of intialising `MapReduceChain` chain
doesn't work if prompt has multiple inputs. It happens because it uses
`StuffDocumentsChain` and `MapReduceDocumentsChain` underneath, both of
them require specifying `document_variable_name` if `prompt` of their
`llm_chain` has more than one `input`.

With this PR, I have added support for passing their respective `kwargs`
via the `from_params` method.
