Missing "/" in GPG URL for RHEL bases OS

[kanisae]

When attempting to install on CentOS 7, I was getting 404 errors during the yum transaction like below:

`Error: /Stage[main]/Bareos::Client/Package[bareos-filedaemon-python-plugin]/ensure: change from purged to present failed: Execution of '/bin/yum -d 0 -e 0 -y install bareos-filedaemon-python-plugin' returned 1: warning: /var/cache/yum/x86_64/7/bareos/packages/bareos-filedaemon-17.2.4-9.1.el7.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 093bfba2: NOKEY

GPG key retrieval failed: [Errno 14] HTTP Error 404 - Not Found`

Looking into it, the URL was missing a "/" in repository.pp, here is my diff of fixing it.
