Fix processing lsif dump with repeating lines with inVs

Closes #305

See merge request gitlab-org/gitlab-workhorse!621

Rewrite processing of lines with "label":"contains" and "label":"item"
for appending for arrays instead override then when lines repeat few times
with equal outV.

Update Gitaly module dependency

See merge request gitlab-org/gitlab-workhorse!619

This updates Gitaly's latest Protocol Buffer definitions, which were
last updated in Feburary 2020, with the latest version of Gitaly. This
is needed to support a new flag (`IncludeLfsBlobs`) in the
`GetArchiveRequest` RPC.

Because we started tagging Gitaly versions `v13.x.x` instead of
`v1.x.x`, `go get` refuses to update the Gitaly module using the latest
tag or SHA (https://gitlab.com/gitlab-org/gitaly/-/issues/3177).  Go
tries to enforce semantic compatibility by requiring the use of module
paths (e.g. `m/v13`), and Gitaly doesn't adhere to this scheme.

To workaround this issue, we use the replace directive
(https://github.com/golang/go/wiki/Modules#when-should-i-use-the-replace-directive):

```
go mod edit -replace gitlab.com/gitlab-org/gitaly=gitlab.com/gitlab-org/gitaly@3f5e218def93024f3aafe590c22cd1b29f744105

Fix correlation IDs not being propagated in preauth check

See merge request gitlab-org/gitlab-workhorse!607

Previously `info/refs`, `upload-pack`, `receive-pack`, and anything that
needed to make an authorization check with Rails would not forward along
the correlation ID injected in the request context. We solve this by
creating the HTTP request with the same context. This adds some
additional memory allocations for each outbound request.
