Increasing replication factor for a topic

1. Create a custom reassignment plan (see attached file inc-replication-factor.json). In this case we are going from replication factor of 1 to 3.

# This config came around after a friend had problems with a Steam cache on his
# Cox internet connection. Cox would intercept any requests to Steam content
# servers and return a 302 to Cox's servers. The cache would return the 302
# to the Steam client, and the Steam client would go directly to Cox, bypassing
# the cache.
# This config makes nginx follow the 302 itself, and caches the result of the
# redirect as if it was the response to the original request. So subsequent
# requests to the URL that returned a 302 will get the file instead of a 302.
