ResponseError from pipelines can be extremely large

[rohansingh]

When a pipeline command results in a ResponseError, both Pipeline and ClusterPipeline include the entire original command in the exception message:

redis-py/redis/client.py

Line 1504 in ceb12fe

f"Command # {number} ({cmd}) of pipeline "

redis-py/redis/asyncio/cluster.py

Line 1596 in ceb12fe

f"Command # {cmd.position + 1} ({command}) of pipeline "

This exception can be extremely large, especially for commands that are sending a large blob to Redis. It would probably suffice to only include a snippet.

Thanks for reaching out! It makes sense to trim it
