s3Store: Concurrently write upload parts to S3 while reading from client (#402)
* Allow empty metadata values
* Make tests less fragile by allowing loose call ordering
* Add s3ChunkProducer
* Integrate s3ChunkProducer to support chunk buffering
* Remove completed chunk files inline to reduce disk space usage
* Add tests for chunk producer
* docs: Use value from Host header to forward to tusd
* Use int64 for MaxBufferedParts field
* Default to 20 buffered parts
* Rename s3ChunkProducer -> s3PartProducer
* Document s3PartProducer struct
* Clarify misleading comment
* Revert "Remove completed chunk files inline to reduce disk space usage"
This reverts commit b72a4d43d6.
* Remove redundant seek
This is already being done in s3PartProducer.
* Clean up any remaining files in the channel when we return
* Make putPart* functions responsible for cleaning up temp files
* handler: Add tests for empty metadata pairs
* Factor out cleanUpTempFile func
* Add test to ensure that temporary files get cleaned up
