Fix TestLogsFileRecreate.

[adam-mateen]

Description of the issue

TestLogsFileRecreate() intermittently fails on Windows OS.
example: https://github.com/aws/amazon-cloudwatch-agent/runs/4156147013?check_suite_focus=true

There are actually 2 issues.
First is that there is a for loop that will does not end until Go does a panic.
Second, the delay between deleting the monitored temp file and recreating it is a fixed 100 ms.
These 2 changes are minimally required.

Description of changes

The loop will timeout after 10 seconds if the LogSrc is not found, instead of Panic after 10 minutes.
The fixed delay between deleting and recreating the temp file has been increased from 100ms to 1 second.

I added some info messages to describe what the test is doing.
I was just going to add code comments, but logging what the test is doing makes it easier to correlate with what the functions being tested are doing and correlate with if/when errors occur.
