Updating gitaly cluster to use a shorter automatic reconciliation duration
Automatic reconciliation (introduced GitLab 13.4) for Praefect defaults to 5 minutes, which can make our tests that are dependant on reconciliation quite slow.
Setting the configuration configuration value to a much shorter time period will help speed our test suite up.
