https download fails with errors such as...
00:21:13.479 ERROR: cannot verify opendev.org's certificate, issued by
‘/C=US/O=Let's Encrypt/CN=R3’:
00:21:13.479 Issued certificate has expired.
The upstream root certificate expire on Oct 1, 2021.
ca-certificates needs to be updated to version 2021.2.50
but that version is only available in Centos 7.9 or newer.
This build container is locked down to Centos 7.8 without
updates.
This update adds repo definitions for 7.9 and 7.8 updates,
but sets them to disabled by default.
When updating ca-certificates I temporarily enable the
Centos 7.9 updates repo.
I also disable the yum module that causes the
"system is not registered with an entitlement server"
messages, but those messages turned out to NOT be the root
cause of ca-certificates failure to update.
