Run periodic checks on specific repos

The periodic checks are useful, as a single point of notification about
for failures, however, the current configuration checks for every repo
in the infrastructure namespace. By doing this, it spot known issues
with low priority, which could lead to confusions and miss important
reports.

Change the configuration to focus in the important repos.
