feat(storage): Create OTel tracing decorator for client:: WriteObject()

[shubham-up-47]

Moving some implementation logic of the method WriteObjectImpl from client.cc file to connection_impl.cc file, so that complate tracing of client:: WriteObject can be enabled (#11394).

Hi @ddelgrosso1, I raised this PR for the feature request #11394.

In this, I am logging a new trace WriteObject/WriteObjectBufferSize from the WriteObjectImpl implementation (along with the existing traces of WriteObject api).

Does this trace look okay for that feature request?

Including @bajajneha27 too. WDYT?

Looks like you're only moving the implementation of WriteObjectBufferSize. Is that intentional?

Yes, It is intentional so that we can have a unique trace which is emitted by the WriteObject api call only.

The traces (like UploadChunk, CreateResumableUpload) which are emitted by the WriteObject api call currently, are emitted in other api calls too, that's why there is no unique otel trace emitted by WriteObject api call.

To have that, i was proposing the trace WriteObjectBufferSize here. If this doesn't look good, we can have another method something like SetupObjectWriteStream or InitializeObjectWriteStreamParams to initialize all the params of the next function call (i.e. ObjectWriteStream), currently i was initializing only one param of the next method call.

Created a struct ObjectWriteStreamParams and using method SetupObjectWriteStream to initialize all the params of the next function which emits the WriteObject/SetupObjectWriteStream trace. This approach looks better to me, please have a look.

@shubham-up-47 As discussed offline, I think the task is to add a span for the WriteObject as a whole operation which we're missing right now.
