puppet-webhook 2.1.1 shows warning during installation on CentOS 7

[bastelfreak]

Hi,
I just tried the installation on a new CentOS 7 node. During this I see the following warning:

...
Using yard 0.9.24
Bundle complete! 38 Gemfile dependencies, 123 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.

That is the gem we need to update to fix the BigDecimal issues, but I believe there are some changes to be aware of before we can just upgrade active_support since it'll will be a major version update
