ansible: remove firewalld on centos and fedora

[santigimeno]

So it doesn't interfere with multicast tests.

Refs: libuv/libuv#2185

Any estimate when this could be included. It'll be great in order to have a greener libuv ci. Thanks!

@santigimeno the challenge is that even once it lands it will only take effect once somebody runs it on all of the relevant machines. That I believe is a multi-hour job....

[rvagg]

yes, sorry, this is near the top of my TODO list, haven't lost track of it, just need a bit of time to execute it with a clear head

[santigimeno]

Ok. Thanks for the prompt response.

[vtjnash]

Do you mind if I bump this?

[rvagg]

don't mind at all, this had slipped low in my list! ... which is getting a bit out of hand again so I probably should dedicate a day or two to clearing my backlog. Will try and get to this soon.

with https://github.com/nodejs-private/secrets/pull/52 & #1977 this will be final, I merged this particular commit in 821de09 but it needed the additional cleanup in #1977 to run. It's been run against the fedora and centos hosts now and it appears to be working, see #1971

[santigimeno]

Thanks!
