[AzDatalake] File Client Upload/Download Support (#21261)

* Enable gocritic during linting (#20715)

Enabled gocritic's evalOrder to catch dependencies on undefined behavior
on return statements.
Updated to latest version of golangci-lint.
Fixed issue in azblob flagged by latest linter.

* Cosmos DB: Enable merge support (#20716)

* Adding header and value

* Wiring and tests

* [azservicebus, azeventhubs] Stress test and logging improvement (#20710)

Logging improvements:

* Updating the logging to print more tracing information (per-link) in prep for the bigger release coming up.
* Trimming out some of the verbose logging, seeing if I can get it a bit more reasonable.

Stress tests:

* Add a timestamp to the log name we generate and also default to append, not overwrite.
* Use 0.5 cores, 0.5GB as our baseline. Some pods use more and I'll tune them more later.

* update proxy version (#20712)

* Return an error when you try to send a message that's too large. (#20721)

This now works just like the message batch - you'll get an ErrMessageTooLarge
if you attempt to send a message that's too large for the link's configured
size.

NOTE: there's a patch to `internal/go-amqp/Sender.go` to match what's in go-amqp's
main so it returns a programmatically useful error when the message is too large.

Fixes #20647

* Changes in test that is failing in pipeline (#20693)

* [azservicebus, azeventhubs] Treat 'entity full' as a fatal error (#20722)

When the remote entity is full we get a resource-limit-exceeded condition. This isn't something we should keep retrying on and it's best to just abort and let the user know immediately, rather than hoping it might eventually clear out.

This affected both Event Hubs and Service Bus.

Fixes #20647

* [azservicebus/azeventhubs] Redirect stderr and stdout to tee (#20726)

* Update changelog with latest features (#20730)

* Update changelog with latest features

Prepare for upcoming release.

* bump minor version

* pass along the artifact name so we can override it later (#20732)

* [azeventhubs] Improperly resetting etag in the checkpoint store (#20737)

We shouldn't be resetting the etag to nil - it's what we use to enforce a "single winner" when doing ownership claims.

The bug here was two-fold: I had bad logic in my previous claim ownership, which I fixed in a previous PR, but we need to reflect that same constraint properly in our in-memory checkpoint store for these tests.
