Description of changes:
Adds default checksum calculation, deprecates the AddContentMD5 config option as S3 plans to deprecate MD5 checksums soon, adds two S3 client config options: request_checksum_calculation and response_checksum_validation with acceptable values for both being either when_supported or when_required.

request_checksum_calculation will default to when_supported, which means if an operation supports checksum calculation (indicated via modeling), the SDK will calculate the checksum and add the appropriate header. If it is set to when_required, the SDK will only compute and send a checksum when the operation requires an httpRequestChecksum.

response_checksum_validation also defaults to when_supported, which means if an operation models response algorithms, an attempt to validate a response checksum will be made. when_required will only validate response checksums when response checksum are modeled AND ChecksumMode is set to enabled on the command.

Overall looks good. Just some minor changes. I also did not see a test for when generating a presigned url with PUT operations and the checksum here should be omitted?
