promoted-components dirs get reaped and the top-level file does not contain all components

[Ronelle Landy]

The promoted-components directories within some of the component directories have not been updated for a few days. This is due to the augmented component pipeline that now runs more jobs per component and therefore produces some failed tests.

The job that promotes component-ci-testing to promoted-components checks the promotion criteria and fails if the test jobs failed therefore not updating the promoted-components link.

After a few days the promoted-components dir disappears and then the top level https://trunk.rdoproject.org/centos8-master/promoted-components/delorean.repo only contains some of the components - the ones with promoted-components directories. Currently, the file only has:

[delorean-component-baremetal]

[delorean-component-clients]

[delorean-component-security]

[delorean-component-swift]

[delorean-component-ui]

It is possible that when we unpin, several component pipeline tests will fail for some time.

The top level https://trunk.rdoproject.org/centos8-master/promoted-components/delorean.repo file should always contain all the components - no matter how long each component hash has been there for.
Therefore the promoted-components directories within components should not be removed.

The root cause for this one is the same as in https://bugs.launchpad.net/tripleo/+bug/1866543, so it is already fixed by the patch to puppet-dlrn.

As for getting the promoted-components/delorean.repo in a healthy state today, we need to restart the per-component pipelines. Once an initial component-ci-testing -> promoted-components promotion is done for every component, we should not see this issue anymore.
