This bug was initially created as a copy of Bug #1591627
I am copying this bug because:
This feature is not available on RHEL8 (microdnf-3.0.1-1.el8).
1. Proposed title of this feature request
>Include --releasever as an option for microdnf
2. Why does the customer need this? (List the business requirements here)
>a. Set release allows them to ensure that they keep working with the same versions of packages and have no untracked changes.
>b. The use of atomic image is preferable over rhel7 image for them in order to make container as tiny as possible.
Option --releasever was introduced by commit https://github.com/rpm-software-management/microdnf/commit/594f4ae5fdd60215a5010526406a34536472bb30.
