Filter any parameters ending with "key" in logs

Use gitlab-ui loading icon

See merge request gitlab-org/gitlab-ce!21659

Rails does a partial match for strings in the filter_parameters
configuration, so the parameter "key" causes "key_id" to be filtered
even though it's a useful parameter for debugging internal API issues.

We now revise this filter to make any parameter ending with "key" is
filtered.

Add stub methods for FakeApplicationSetting

This gives admins the ability to send a `skip_confirmation` flag in the
`POST /users/:id/email` API endpoint to skip the verification step and
assume the given e-mail address is verified.

Closes #50876

In a migration spec, a default ApplicationSetting object may fail to
create due to an unknown attribute and fall back to
FakeApplicationSetting.  FakeApplicationSetting appears to be missing a
number of methods that are needed
(https://gitlab.com/gitlab-org/gitlab-ce/issues/47491). This commit adds
the ones needed to make an EE spec pass.
