`CloudWatch logs have not completed ingestion within 1 minute`

[omus]

I've noticed this failure show up a few times with the online tests:

 Num workers (10): Error During Test at /home/runner/work/AWSClusterManagers.jl/AWSClusterManagers.jl/test/batch_online.jl:122
  Got exception outside of a @test
  CloudWatch logs have not completed ingestion within 1 minute
  Stacktrace:

   [2] run_batch_job(::String, ::Int64; timeout::Minute, should_fail::Bool) at /home/runner/work/AWSClusterManagers.jl/AWSClusterManagers.jl/test/batch_online.jl:109

The logs for the manager:

The issue is that the check assumes the "Manager Complete" message will be the last thing written to the logs
