[EMBR-2802] Fix race condition on LogSink and LogOrchestrator.

[lucaslabari]

Goal

• Converted the list on LogSink into a ConcurrentLinkedQueue to use thread-safe operations.
• Added a lock on the flush method, so no more than one thread can execute the flush at the same time.
• Added a param to the flushLogs method to provide the max number of logs to flush.
• Converted properties that hold time in LogOrchestrator to AtomicLong.

Testing

Added a method created by Hanson to emulate the race condition.

LGTM! One comment about simplifying the flush logic but feel free to take it or leave it
