Flaky integration tests: Could not acquire locks

[burkedavison]

Example:
https://github.com/GoogleCloudPlatform/spring-cloud-gcp/actions/runs/8900902697/job/24443534158

Anecdotally, this has been happening in many different modules' integration tests in Spring Cloud GCP. The above is only one example.

Error:  Could not acquire lock(s)
Error:  java.lang.IllegalStateException: Could not acquire lock(s)
Error:  Could not acquire lock(s)
Error:  Could not acquire lock(s)
Error:  Could not acquire lock(s)
Error:  Could not acquire lock(s)

https://issues.apache.org/jira/browse/MNG-7868 appears to be related and there doesn't seem to be an easy fix. We might have to wait for Maven to fix the issue.
