What does this PR do?
It resets the config synchronisation (sync.Once) in order to not affect other tests.
Why is it important?
I found this issue as a side effect of debugging another thing, and it took me a couple of hours to understand that the testcontainers.properties file was empty because somebody in the test execution called the ReadConfig() method, initialising the
sync.Oncethat protects from multiple reads of the config.I noticed the HOME variable was empty when reading the Docker Host, os.UserHomeDir returned an error, and that led me to identify the config as the culprit. Following the rabbot hole I found there were two tests reading the config but not resetting the original state (only available for internal use of the library), and this PR fixes that.
