There is a problem detecting some file types like SVG. Depending
on how the file is built, it will detect the right content type
or not. For example, if the SVG file has a big html comment
(more than 512 bytes) at the beginning of it, when we start
the detection process we'll get the first 512 bytes and based on
that we will set the content type `text/plain`. But this is wrong
because the file is indeed an SVG.

Update gitaly-proto to v1.10.0

See merge request gitlab-org/gitlab-workhorse!364

GitLab 11.8.0 added a new field `glProjectPath` that is erroring out
when generating diffs. We need to keep gitaly-proto in sync with CE/EE
to avoid these issues.

Adds X-Request-Id response header for Workhorse

See merge request gitlab-org/gitlab-workhorse!363

This change configures workhorse to set the Correlation-ID value in
the response header. This is a common technique which allows errors to
be traced more easily.

This can be done through several methods: 1) users can review their
browser headers and report the value 2) nginx error pages could be
configured to report the correlation-id on the error page, allowing
users to easily report it.

Once the correlation-id has been reported, support engineers or
production staff can use this to further investigate issues using
logging infrastructure, sentry or distributed tracing.

Version 8.3.0

Support encoded Content-Disposition fields

Closes #207

See merge request gitlab-org/gitlab-workhorse!360

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/24919/diffs adds
support for Rails sending the right `Content-Disposition` header when
there are non-ASCII filenames (e.g. `テスト.txt`). That example file
would render the following Content-Disposition:

```
attachment; filename="テスト.txt", filename*=UTF-8''%E3%83%86%E3%82%B9%E3%83%88.txt
```

Since mime.ParseMediaType appears to strip this header to a canonical
filename, it's not possible to use this to generate the right
Content-Disposition. Instead, we can preserve the existing
Content-Disposition and convert types just by doing a search and replace
(i.e. change `attachment` to `inline` and vice versa when necessary).

Count ^/-/ requests separately in prometheus

Closes #204

Statically link jaeger into Workhorse by default

See merge request gitlab-org/gitlab-workhorse!359

This change will statically compile the jaeger client into workhorse
by default. This will allow support staff to enable the
`GITLAB_TRACING` variable to investigate issues further.

Note that by default, this will not enable tracing, only compile the
client in.

Release v8.2.0

Upgrade Gitaly Proto to use gitalypb

See merge request gitlab-org/gitlab-workhorse!331

This is a version than includes the new gitaly-proto, which has the
package name changed. Now gitalypb is used everywhere. The client of
Gitaly is updated too, as only one proto definition can register a type.
