currently reflected in the state of the product.

Docs: Updating style of note

See merge request gitlab-org/gitlab!49267

Adds guest package events to usage data

See merge request gitlab-org/gitlab!48734

AWS will complain if no Content-Length is not specified, so we need to
use multipart URLs if no length is available.

The Workhorse S3 client handles multipart uploads in a much more robust
way. We don't need to generate pre-signed URLs when it is used.

When pre-signed multipart URLs are generated and the max size is 0,
previously the code would error out while calculating the URLs.

We now handle this case by assuming the file is the maximum number of
parts.

Refactor Git/LFS request specs into shared examples

See merge request gitlab-org/gitlab!49138

This allows us to reuse them in EE.

- The shared examples for `Repositories::GitHttpController` were moved
  without any changes.

- The LFS request specs were cleaned up and simplified a bit.

Epic, even though is using the issuable components,
doesn't follow the same pattern of sanitization of the
HTML data at the moment the data is read. This leads to
double-rendering of the Vue applications when description
content fetched with polling doesn't match the initial
one. Even though the difference is purely cosmetic
(stripped out line breaks in the initial description),
Vue still updates state and rerenders the view seeing
that the description is different.

This MR fixes this and unifies the way we sanitize output
for Issues and Epics
