A user that needs to have cdn.redhat.com in their /etc/hosts file to properly resolve the CDN gets that entry removed when satellite-clone is run, leading to a failed installation of Satellite.

Version-Release number of selected component (if applicable):
HTB

How reproducible:
Always

Steps to Reproduce:
1. Create a host that can't resolve cdn.redhat.com (e.g. by disabling dns)
2. Add an entery in /etc/hosts for cdn.redhat.com
3. Run satellite-clone

Actual results:
TASK [satellite-clone : Install Satellite 6.2 packages] ************************************************
fatal: [localhost]: FAILED! => {"changed": false, "failed": true, "msg": "[Errno -3] Temporary failure in name resolution\nhttps://cdn.redhat.com/content/dist/rhel/server/7/7Server/x86_64/os/repodata/repomd.xml: [Errno 14] curl#6 - \"Could not resolve host: cdn.redhat.com; Temporary failure in name resolution\"\nTrying other mirror.\n\n\n One of the configured repositories failed (Red Hat Enterprise Linux 7 Server (RPMs)),\n and yum doesn't have enough cached data to continue. At this point the only\n safe thing yum can do is fail. There are a few ways to work \"fix\" this:\n\n     1. Contact the upstream for the repository and get them to fix the problem.\n\n     2. Reconfigure the baseurl/etc. for the repository, to point to a working\n        upstream. This is most often useful if you are using a newer\n        distribution release than is supported by the repository (and the\n        packages for the previous distribution release still work).\n\n     3. Disable the repository, so yum won't use it by default. Yum will then\n        just ignore the repository until you permanently enable it again or use\n        --enablerepo for temporary usage:\n\n            yum-config-manager --disable rhel-7-server-rpms\n\n     4. Configure the failing repository to be skipped, if it is unavailable.\n        Note that yum will try to contact the repo. when it runs most commands,\n        so will have to try and fail each time (and thus. yum will be be much\n        slower). If it is a very temporary problem though, this is often a nice\n        compromise:\n\n            yum-config-manager --save --setopt=rhel-7-server-rpms.skip_if_unavailable=true\n\nfailure: repodata/repomd.xml from rhel-7-server-rpms: [Errno 256] No more mirrors to try.\nhttps://cdn.redhat.com/content/dist/rhel/server/7/7Server/x86_64/os/repodata/repomd.xml: [Errno 14] curl#6 - \"Could not resolve host: cdn.redhat.com; Temporary failure in name resolution\"\n", "rc": 1, "results": []}


Expected results:
Satellite is installed correctly.


Additional info:
Current workaround is to disable the /etc/hosts task in the clone playbook.
