[EmilNadimanov]

🔧 Type of changes

• bid adapter update
• new feature
• new analytics adapter
• new module
• module update
• bugfix
• documentation
• configuration
• dependency update
• tech debt (test coverage, refactorings, etc.)

✨ What's the context?

#3718 Porting the FeedAd Bidder Adapter

🧠 Rationale behind the change

Keeping prebid-server-java up to date

🔎 New Bid Adapter Checklist

• verify email contact works
• NO fully dynamic hostnames
• geographic host parameters are NOT required
• direct use of HTTP is prohibited - implement an existing Bidder interface that will do all the job
• if the ORTB is just forwarded to the endpoint, use the generic adapter - define the new adapter as the alias of the generic adapter
• cover an adapter configuration with an integration test

🧪 Test plan

How do you know the changes are safe to ship to production?
Unit tests + an integration test for the happy case

🏎 Quality check

• Are your changes following our code style guidelines?
• Are there any breaking changes in your code?
• Does your test coverage exceed 90%?
• Are there any erroneous console logs, debuggers or leftover code in your changes?

Hi folks,

The functional test seems unrelated to this port.

Functional test failure is due to a flaky test, so it can be ignored for the purpose of this PR.

@EmilNadimanov failed IT test

Huh, I didn't make any changes to the fixtures, the test or the Bidder Adapter. And it works locally. I will take a look, in the meantime I've updated the branch to be up to date with upstream master
UPD: ok, it fails locally as well after I pulled the changes from upstream. Working on it.
UPD2: ah, I needed to add meta info with the adapter code to the bid extension because of #3855
