Implement database query and view for showing latest API backends

[bajiat]

As a part of the front-page re-design we need a view of the newest additions to API catalog. This requires both a query (publication and subscription) and a view.

• Create publication
• Create subscription
• Create temporary route (For testing purposes, until home page is redesigned)
• Create template
• Use specific query that contains sorting by created_at field & limit amount of returned documents, for example to 6.
• Integrate latestApiBackends template to a redesigned home page.

Interested in this one.

[bajiat]

@frenchbread Are you still interested? Might require a schema update so that we have a creation date for API backends.

[frenchbread]

Self-assigned.

Creation timestamp field for API backends should be already present in a schema.

Created a PR #727 with WIP label.

The reason for WIP label is that since we do not have a redesigned version of a home page yet, there is no actual place where to put latestApiBackends template. For that reason I've added a temporary route /latest for testing.

Does it make sense to keep the PR in WIP until the new design is submitted? Or we can merge it now and do related integrations later?
