Review Comment:
why is this going in here when like 1085 sets this header too?

> Azure Storage Supports Content-MD5 Request Headers in Both Read and Append
> APIs.
> Read: [Path - Read - REST API (Azure Storage Services) | Microsoft
> Learn|https://learn.microsoft.com/en-us/rest/api/storageservices/datalakestoragegen2/path/read]
> Append: [Path - Update - REST API (Azure Storage Services) | Microsoft
> Learn|https://learn.microsoft.com/en-us/rest/api/storageservices/datalakestoragegen2/path/update]
> This change is to make client-side changes to support them. In Read request,
> we will send the appropriate header in response to which server will return
> the MD5 Hash of the data it sends back. On Client we will tally this with the
> MD5 hash computed from the data received.
> In Append request, we will compute the MD5 Hash of the data that we are
> sending to the server and specify that in appropriate header. Server on
> finding that header will tally this with the MD5 hash it will compute on the
> data received.
> This whole Checksum Validation Support is guarded behind a config, Config is
> by default disabled because with the use of "https" integrity of data is
> preserved anyways. This is introduced as an additional data integrity check
> which will have a performance impact as well.
> Users can decide if they want to enable this or not by setting the following
> config to *"true"* or *"false"* respectively. *Config:
> "fs.azure.enable.checksum.validation"*
