Updated the "load_memory_variables" function of the
ConversationBufferWindowMemory to support a window size of 0 (k=0).
Previous behavior would return the full memory instead of an empty
array.
The new functionality of Redis backend for chat message history
([see](https://github.com/hwchase17/langchain/pull/2122)) uses the Redis
list object to store messages and then uses the `lrange()` to retrieve
the list of messages
([see](https://github.com/hwchase17/langchain/blob/master/langchain/memory/chat_message_histories/redis.py#L50)).
Unfortunately this retrieves the messages as a list sorted in the
opposite order of how they were inserted - meaning the last inserted
message will be first in the retrieved list - which is not what we want.
This PR fixes that as it changes the order to match the order of
insertion.

1. Removed the `summaries` dictionary in favor of directly appending to
the summary_strings list, which avoids the unnecessary double-loop.
2. Simplified the logic for populating the `context` variable.

Provide shared memory capability for the Agent.
Inspired by #1293 .
## Problem
If both Agent and Tools (i.e., LLMChain) use the same memory, both of
them will save the context. It can be annoying in some cases.
## Solution
Create a memory wrapper that ignores the save and clear, thereby
preventing updates from Agent or Tools.
