Fix karma junit result formatter

See merge request gitlab-org/gitlab-ce!21744

Because we were passing query strings as symbols, the fog-aws storage
driver was omitting the uploadId and partNumber query strings
from the signature in multipart uploads. This fix makes AWS and Ceph work with
v2 signatures.

Closes #51412

See merge request gitlab-org/gitlab-ce!21697

In https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/19625 some
changes were introduced that do not meet our abstraction reuse rules.
This commit cleans up some of these changes so the requirements are met.

Most notably, sorting of the runners in Admin::RunnersFinder has been
delegated to Ci::Runner.order_by, similar to how we order data in
models that include the Sortable module. If we need more sort orders in
the future we can include Sortable and have Ci::Runner.order_by call
`super` to delegate to Sortable.order_by.

By default, we now strip images in the 'first_line_in_markdown'
method.  This keeps images from being displayed in the
one-liner of both todo and project activity panels.

Although not currently used, we allow images to be preserved
with the allow_images: true options.
