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.

This relaxes the commit rules regarding the number of changed lines.
Previously we required a detailed description if 20 or more lines were
changed. Starting with this commit we change the rules so Danger only
notifies you about writing a detailed description if:

1. A commit changes more than 3 files
2. The same commit changes more than 30 lines

This should make it easier to do a find replace to fix a typo, without
having to repeat what the subject line already says, while still
reminding developers to write a detailed description for new features
and other larger changes.
