timeout param issue in mod::proxy

[robertc99]

Version 8 has set the type of apache::mod::proxy::proxy_timeout as undef or string. It should be undef or integer.
proxy_iobuffersize should probably also be integer.

So this is:

puppetlabs-apache/manifests/mod/proxy.pp

Line 33 in 92865b3

Optional[String] $proxy_timeout = undef,

The docs are https://httpd.apache.org/docs/2.4/mod/mod_proxy.html#proxytimeout and those say it is in seconds, so Integer makes sense. Probably even Integer[0] since negative values are unsupported AFAIK.

Could you come up with a PR?

Fixed in #2294
