ubi8: daemon-base: install without docs

[mykaul]

In a container, there's no need to install documentation.
Pass the relevant option for yum to skip documentation installation

CI failure is on:
"Error: Failed to synchronize cache for repo 'lab-extras'"
which is true - I can't reach http://apt-mirror.front.sepia.ceph.com/ either :(

So some infra issue.

While I agree with this I think this should be done:

1. not on the yum/dnf CLI but in the configuration.
2. not only for ubi8 but CentOS 8 too.

And ultimately this should be part of the base image like it is currently present for RHEL/ubi7 and CentOS 7.
I'm wondering why this is not included by default in the latest major release. Maybe dnf set this by default now.

$ docker run --rm centos:7 grep tsflags /etc/yum.conf
tsflags=nodocs
$ docker run --rm centos:8 grep tsflags /etc/yum.conf$ docker run --rm centos:8 grep tsflags /etc/yum.conf
$ docker run --rm registry.access.redhat.com/rhel7 grep tsflags /etc/yum.conf
tsflags=nodocs
$ docker run --rm registry.access.redhat.com/ubi7/ubi:latest grep tsflags /etc/yum.conf
tsflags=nodocs
$ docker run --rm registry.access.redhat.com/ubi8/ubi:latest grep tsflags /etc/yum.conf
$

For me this should be only a workaround until this is fix in the base image.

For CentOS 7 this is done here [1] but for some reason the same thing isn't present in CentOS 8 [2].

this has been resolved

Asked the CentOS team about 8 - CentOS/sig-cloud-instance-build#167

Of course it should be added to CentOS 8 - thought I'd start with UBI first though.

Not sure why it should be a configuration item, though.

Not sure why it should be a configuration item, though.

To avoid adding new yum/dnf commands without this option and because that's the way it's done on ubi 7.
