Expected a numeric value for http01_port

[schoen]

Forum user Randall describes this problem when using letsencrypt renew:

...The error was Expected a numeric value for http01_port. ...
Editing the file /etc/letsencrypt/renewal/[my.domain].conf file solved this problem. I changed http01_port = None to http01_port = 80

@bmw said that this would have been fixed (in terms of renewal config files correctly specifying http01_port) back in November, but people who have older lineages than that may have this problem when renewing with standalone. That could conceivably be a pretty large number of users!

For reference, this was the commit that changed the behavior: bb6736f

Looks like we had a similar problem before when renewer.py tried to cast the value to an int.

A number of people are still having trouble with this (we just had another report on the forum).

Hopefully nobody will be troubled by this bug anymore thanks to @bmw's PR. I'll try to let some people know on the forums and confirm that it works for them.
