Add logging for local LSIF ZIP caching

Support Azure custom storage domains

See merge request gitlab-org/gitlab-workhorse!593

Users of Azure Blob storage, particularly those using Azure China, Azure
Germany, or Azure Government, may need to customize the Azure
endpoint. To support this, we add a custom Azure URL opener that
supports the `domain` query parameter. This work has been submitted
upstream: https://github.com/google/go-cloud/pull/2851/files

Documentation for using Azure Blob storage:

Drop tests that check for log messages

See merge request gitlab-org/gitlab-workhorse!591

logrus starts a Goroutine to write messages to the output buffer, but
there is no way to flush these messages to ensure they are ready
(https://github.com/sirupsen/logrus/issues/435). To avoid race
conditions, drop these log checks from our tests.

Use maximum size to reject file upload as needed

See merge request gitlab-org/gitlab-workhorse!554

Eliminate unnecessary code in GoCloud test stubs

See merge request gitlab-org/gitlab-workhorse!590

This should eliminate a race condition that only occurred in the test
where multiple Goroutines attempt to write to the same value when
opening a bucket.

Silence errors when Azure objects have aleady been deleted

Fix objectstore.uploader.uploadError race

See merge request gitlab-org/gitlab-workhorse!583

In an normal upload flow, GitLab Rails will move a file to its final
destination and remove the temporary file. Workhorse issues a DELETE a
request to ensure this is cleaned up. Previously this was generating log
noise with every upload. Now only log an error message if there were
some error other than a 404.

The `So(server, ShouldNotBeNil)` call in the httprs test attempts to
print a string representation of the `server`, but this is racy because
the reconnection state is initialized in a
Goroutine. `httptest.NewServer()` always returns a valid value, so we
can drop this test.
