yum_repository is not importing gpg keys as stated in the documentation

[BasLangenberg]

Description

In the documentation, it is stated that for the yum_repository provider gpgkey option, that "If this option is set, Yum will automatically import the key from the specified URL."

Investigation shows that this is not the case and I cannot find evidence that Chef is downloading GPG keys in the source code.

Chef Version

Chef: 14.13.11

Platform Version

Redhat 7.6

Replication Case

Minimal Chef recipe:

yum_repository 'epel' do
  action :create
  description 'Fedora EPEL Repository'
  metalink 'https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearch'
  failovermethod 'priority'
  gpgcheck true
  gpgkey 'http://download.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL'
  enabled true
end

Checking the imported rpm keys afterwards will not show the gpg keys added to the system.

[vagrant@default-centos-7 ~]$ rpm -q gpg-pubkey --qf '%{NAME}-%{VERSION}-%{RELEASE}\t%{SUMMARY}\n'
gpg-pubkey-f4a80eb5-53a7ff4b    gpg(CentOS-7 Key (CentOS 7 Official Signing Key) <security@centos.org>)

Reproduced in CentOS on Vagrant, and in a 'real' server running RHEL. Both version 7.6.

Seems like that property was never implemented at all
