Old logs and 24h batching limit

[alexeykaplin]

I am getting lots of errors on an initial log sync:
time="2019-11-25T11:46:49Z" level=error msg="[cloudwatch 0] InvalidParameterException: The batch of log events in a single PutLogEvents request cannot span more than 24 hours.\n\tstatus code: 400, request id: 9e371dc0-5efe-4803-91d9-e779cb6bc165\n"

Possible solution is an appropriate duration limiter, it can be introduced here:

amazon-cloudwatch-logs-for-fluent-bit/cloudwatch/cloudwatch.go

Line 207 in 83d185c

if len(stream.logEvents) == maximumLogEventsPerPut || (stream.currentByteLength+cloudwatchLen(event)) >= maximumBytesPerPut {
