feat: implement search v1 endpoint

[juanpicado]

Enable npm search v1 endpoint support by default

• The npm search is able to use two endpoints, the /-all/ and the v1. Unfortunately npm 7 dropped /-/all support and requires v1. This PR add support for v1 .

• npm6 or minor will try to hit v1 and if get 404 will fallback to /-/all endpoint.

• Check for allow_access peer package (if you are using a plugin will ask for every package, even uplinks)

• The experiment search has been removed and v1 is enabled by default.

• Finish v1 search implementation

• Add test

• Add missing security layer

• Support /-/all and v1 at the same time

• Add CLI test

• Remove search experiment

Disclaimer

• The endpoint combines local packages and uplinks, eliminate duplicates and give priority to the ones fetched from uplinks (this could be improved in the next release)
• Uplinks cannot be skipped (this could be improved in the future)
• If the uplinks fails, the endpoint will return 0 results, (this could be improved in the future)

Feedback is welcome (using npm7)

docker run -it --rm --name verdaccio -p 4873:4873 verdaccio/verdaccio:search-v1

It seems just adding the access control #1839 for v1 search. Looks to me now.

Note: We need to copy this logic to master branch.
