Integrate With Automation Pipelines Marketplace

[zarkones]

Disclaimer; It's called a "marketplace", however, all pipelines will be free. Please, suggest any other term. I am considering "automation pipelines repository", however, doesn't sound too good I guess.

As a user I need to be able to visit automation pipelines marketplace in XENA and browse & preview pipelines which I as a user can then import. At the moment uploading pipelines to the marketplace is out of scope of this task particularly.
