Packer build not possible due to not downloadable files

[DennisKonrad]

Hi,

I identified two problems when building via packer. Both downloads time out because the files are not present any more.

==> qemu: Downloading or copying ISO
    qemu: Downloading or copying: http://mirrors.fibergrid.in/centos/7.6.1810/isos/x86_64/CentOS-7-x86_64-NetInstall-1810.iso

Maybe we should change the cmk download to:

wget -O /bin/cmk https://github.com/apache/cloudstack-cloudmonkey/releases/download/6.0.0/cmk.linux.x86-64

Also I changed the iso_url:

"iso_url": "http://centos.mirror.iphh.net/CentOS/7.6.1810/isos/x86_64/CentOS-7-x86_64-Minimal-1810.iso", "iso_checksum": "38d5d51d9d100fd73df031ffd6bd8b1297ce24660dc8c13a3b8b4534a4bd291c",
