This commit adds a resuable UI component that allows a user to search
for a project name, shows the search results, and allows the user to
select one or more projects.  This component communicates with its
parent using props and events.

This component was originally created for use in the EE-specific
"Operations Dashboard" page, but it is applicable for CE use cases as
well, and so was added as a CE shared component.

In addition, some logic was extracted from the frequent_items_list_item
component into shared filters to avoid logic duplication.

Don't try to set any ACL on uploaded objects

Closes #59309

See merge request gitlab-org/gitlab-ce!26781

Set ACL of uploaded objects to not-public (fog-aws) or no ACL at all
(fog-google).  Value is ignored by other supported backends (fog-aliyun,
fog-openstack, fog-rackspace)

This allows uploads to GCS with ACL support disabled.

Fix failing spec in spec/features/users/login_spec.rb

Closes #59731

See merge request gitlab-org/gitlab-ce!26787

This spec would start to fail on the first of the month because the
generated text would have a zero-padded day (e.g. 01 vs 1), whereas the
expected text check used an unpadded day via the `-d` parameter in
strftime (https://apidock.com/ruby/Date/strftime). To fix this, we
use use the `d` parameter to pad zeros.

This spec was introduced recently in
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/25731.
