[Request] Add a method append

[jamesst20]

Hi,

I'm currently using a field in redis to log my worker informations.

This is how I do it currently:

  def log(message)
    store log: (retrieve(:log) || '').concat(message).concat("\n")
  end

It really isn't efficient, it's slow actually. Would it be possible to add a method 'append' or 'store_append' that uses the built in APPEND command from redis https://redis.io/commands/append ?

It probably would be much faster.

Thank you
