chg: [redispub] reading redis responses

[gallypette]

fix #410

[dmachard]

Responses from redis are discarded, it's can not be useful to read it in some cases ?
Otherwise, LGTM.
Thanks again

[gallypette]

The response in this case is the number of clients that consumed the message that was sent. It could be useful to some but I am more in a fire and forget situation regarding these messages.

[dmachard]

Ready to merge ?

[gallypette]

I think so.
My test instance's memory seems sane with this patch so #353 could be considered fixed.

We use it in production and it works as expected.

[dmachard]

Glad to hear that and thanks for your contributions.

Do you plan to share how the DNS-collector is used in your side ?
Usage in production may be useful for others :)
