======================================================================

Description of problem:

See bug 1528813.

ovirt-hosted-engine-cleanup calls 'vdsm-tool remove-config', but this leaves at least some files changed by vdsm with the changes.

First one I noticed is that libvirtd fails to start with:

Dec 24 13:21:57 lvc7host1.home.local libvirtd[16297]: 2017-12-24 11:21:57.641+0000: 16297: error : virNetTLSContextCheckCertFile:120 : Cannot read CA certificate '/etc/pki/vdsm/certs/cacert.pem': No such file or directory

Because /etc/libvirt/libvirtd.conf has:

## beginning of configuration section by vdsm-4.20.0
auth_unix_rw="sasl"
ca_file="/etc/pki/vdsm/certs/cacert.pem"
cert_file="/etc/pki/vdsm/certs/vdsmcert.pem"
host_uuid="88f843a0-fdda-4eb2-bdb4-b6edacd7ad6e"
keepalive_interval=-1
key_file="/etc/pki/vdsm/keys/vdsmkey.pem"
unix_sock_group="qemu"
unix_sock_rw_perms="0770"
## end of configuration section by vdsm-4.20.0

which is not removed, while the cleanup script later does remove vdsmcert.pem , so libvirtd fails to read it.

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

Current master

How reproducible:

Not sure, I think always

Steps to Reproduce:
1. deploy hosted-engine. It's probably enough to 'vdsm-tool configure --force'.
2. vdsm-tool remove-config
3.

Actual results:

All configuration files changed by (1.) are reverted to their original state.

Expected results:

At least some are not.
