Time report

1. Basic server and client implementation 2h
2. Workers implementation 8h
3. Basic test and this report creation 1h

Known issues:

1. missing gzip compression
2. improve solution because current solution blocks requests processing when object parts are delivered to s3. AWS Kinesis Firehose usage looks as more suitable solution to deliver data streams to S3 though it will not allow to meet all requirements regarding objects naming.
3. refactor solution to interfaces to make the code more testable using mocks
4. add more tests
