/**
* <p>
* Uploads a new object to the specified Amazon S3 bucket.
* The PutObjectRequest optionally uploads object metadata
* and applies a canned access
* control policy to the new object.
* </p>
* <p>
* Amazon S3 never stores partial objects;
* if during this call an exception wasn't thrown,
* the entire object was stored.
* </p>
* <p>
* Depending on whether a file or input stream is being uploaded, this
* request has slightly different behavior.
* </p>
* <p>
* When uploading a file:
* </p>
* <ul>
* <li>
* The client automatically computes a checksum of the file.
* Amazon S3 uses checksums to validate the data in each file.
* </li>
* <li>
* Using the file extension, Amazon S3 attempts to determine
* the correct content type and content disposition to use
* for the object.
* </li>
* </ul>
* <p>
* When uploading directly from an input stream, content length <b>must</b> be specified before data can be uploaded
* to Amazon S3. If not provided, the library will <b>have
* to</b> buffer the contents of the input stream in order to calculate it.
* Amazon S3 explicitly requires that the content length be sent in
* the request headers before any of the data is sent.</li>
* <p>
* Amazon S3 is a distributed system. If
* Amazon S3 receives multiple write requests for the same object nearly
* simultaneously, all of the objects might be stored. However, only one object
* will obtain the key.
* </p>
* <p>
* Note: Amazon S3 does not provide object locking; if this is needed, make
* sure to build it into the application layer.
* </p>
* <p>
* If the caller specifies a location constraint when creating a bucket,
* all objects added to the bucket are stored in the same region as the bucket.
* For example, if specifying a Europe (EU) region constraint for a bucket,
* all of that bucket's objects are stored in the EU region.
* </p>
* <p>
* The specified bucket must already exist and the caller must have
* {@link Permission#Write} permission to the bucket to upload an object.
* </p>
