// Adds an object to a bucket. You must have WRITE permissions on a bucket to add
// an object to it. Amazon S3 never adds partial objects; if you receive a success
// response, Amazon S3 added the entire object to the bucket. Amazon S3 is a
// distributed system. If it receives multiple write requests for the same object
// simultaneously, it overwrites all but the last object written. Amazon S3 does
// not provide object locking; if you need this, make sure to build it into your
// application layer or use versioning instead. To ensure that data is not
// corrupted traversing the network, use the Content-MD5 header. When you use this
// header, Amazon S3 checks the object against the provided MD5 value and, if they
// do not match, returns an error. Additionally, you can calculate the MD5 while
// putting an object to Amazon S3 and compare the returned ETag to the calculated
// MD5 value.
//
// * To successfully complete the PutObject request, you must have the
// s3:PutObject in your IAM permissions.
//
// * To successfully change the objects acl
// of your PutObject request, you must have the s3:PutObjectAcl in your IAM
// permissions.
//
// * The Content-MD5 header is required for any request to upload an
// object with a retention period configured using Amazon S3 Object Lock. For more
// information about Amazon S3 Object Lock, see Amazon S3 Object Lock Overview
// (https://docs.aws.amazon.com/AmazonS3/latest/dev/object-lock-overview.html) in
// the Amazon S3 User Guide.
//
// Server-side Encryption You can optionally request
// server-side encryption. With server-side encryption, Amazon S3 encrypts your
// data as it writes it to disks in its data centers and decrypts the data when you
// access it. You have the option to provide your own encryption key or use Amazon
// Web Services managed encryption keys (SSE-S3 or SSE-KMS). For more information,
// see Using Server-Side Encryption
// (https://docs.aws.amazon.com/AmazonS3/latest/dev/UsingServerSideEncryption.html).
// If you request server-side encryption using Amazon Web Services Key Management
// Service (SSE-KMS), you can enable an S3 Bucket Key at the object-level. For more
// information, see Amazon S3 Bucket Keys
// (https://docs.aws.amazon.com/AmazonS3/latest/dev/bucket-key.html) in the Amazon
// S3 User Guide. Access Control List (ACL)-Specific Request Headers You can use
// headers to grant ACL- based permissions. By default, all objects are private.
// Only the owner has full access control. When adding a new object, you can grant
// permissions to individual Amazon Web Services accounts or to predefined groups
// defined by Amazon S3. These permissions are then added to the ACL on the object.
// For more information, see Access Control List (ACL) Overview
// (https://docs.aws.amazon.com/AmazonS3/latest/dev/acl-overview.html) and Managing
// ACLs Using the REST API
// (https://docs.aws.amazon.com/AmazonS3/latest/dev/acl-using-rest-api.html). If
// the bucket that you're uploading objects to uses the bucket owner enforced
// setting for S3 Object Ownership, ACLs are disabled and no longer affect
// permissions. Buckets that use this setting only accept PUT requests that don't
// specify an ACL or PUT requests that specify bucket owner full control ACLs, such
// as the bucket-owner-full-control canned ACL or an equivalent form of this ACL
// expressed in the XML format. PUT requests that contain other ACLs (for example,
// custom grants to certain Amazon Web Services accounts) fail and return a 400
// error with the error code AccessControlListNotSupported. For more information,
// see  Controlling ownership of objects and disabling ACLs
// (https://docs.aws.amazon.com/AmazonS3/latest/userguide/about-object-ownership.html)
// in the Amazon S3 User Guide. If your bucket uses the bucket owner enforced
// setting for Object Ownership, all objects written to the bucket by any account
// will be owned by the bucket owner. Storage Class Options By default, Amazon S3
// uses the STANDARD Storage Class to store newly created objects. The STANDARD
// storage class provides high durability and high availability. Depending on
// performance needs, you can specify a different Storage Class. Amazon S3 on
// Outposts only uses the OUTPOSTS Storage Class. For more information, see Storage
// Classes
// (https://docs.aws.amazon.com/AmazonS3/latest/dev/storage-class-intro.html) in
// the Amazon S3 User Guide. Versioning If you enable versioning for a bucket,
// Amazon S3 automatically generates a unique version ID for the object being
// stored. Amazon S3 returns this ID in the response. When you enable versioning
// for a bucket, if Amazon S3 receives multiple write requests for the same object
// simultaneously, it stores all of the objects. For more information about
// versioning, see Adding Objects to Versioning Enabled Buckets
// (https://docs.aws.amazon.com/AmazonS3/latest/dev/AddingObjectstoVersioningEnabledBuckets.html).
// For information about returning the versioning state of a bucket, see
// GetBucketVersioning
// (https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetBucketVersioning.html).
