As no content will be returned to the client if a root-disable request
succeeds, a HTTP 204 (Not Content) response is more appropriate.
Redis root-disable scenario test fails because it's return HTTP 204, but
all API related tests are expecting a HTTP 200. Although changing Redis
root-disable API is a much simpler way to resolve the problem, migrating
from HTTP 200 to HTTP 204 should be a better solution. Related tests and
documents are also updated accordingly.
