Harshavardhana 7350543f24 Allow x-amz-content-sha256 to be optional for PutObject() (#5340)
x-amz-content-sha256 can be optional for any AWS signature v4
requests, make sure to skip sha256 calculation when payload
checksum is not set.

Here is the overall expected behavior

** Signed request **
- X-Amz-Content-Sha256 is set to 'empty' or some 'value'  or its
  not 'UNSIGNED-PAYLOAD'- use it to validate the incoming payload.
- X-Amz-Content-Sha256 is set to 'UNSIGNED-PAYLOAD' - skip checksum verification
- X-Amz-Content-Sha256 is not set we use emptySHA256

** Presigned request **
- X-Amz-Content-Sha256 is set to 'empty' or some 'value'  or its
  not 'UNSIGNED-PAYLOAD'- use it to validate the incoming payload
- X-Amz-Content-Sha256 is set to 'UNSIGNED-PAYLOAD' - skip checksum verification
- X-Amz-Content-Sha256 is not set we use 'UNSIGNED-PAYLOAD'

Fixes #5339

Harshavardhana 62f8343879 Add constants for commonly used values. (#3588)
This is a consolidation effort, avoiding usage
of naked strings in codebase. Whenever possible
use constants which can be repurposed elsewhere.

This also fixes `goconst ./...` reported issues.
