chore: Drop recipes with unsupported - outdated - PHP versions

[susnux]

• Resolves Drop obsolete versions of PHP #336

Keep the images but drop the recipes as they no longer used and make the repo very crowded.
(This is git if you need them just look in the git log 😉 )

Kind of yolo, but if others agree, I would be fine

Fine by me but not sure if we dont need them later possibly?

The images are preserved, but the recipes are just dropped form master (see referenced issue we dropped support for those versions with NC18 and NC20).

I'd keep 7.1 and above, for the unlikely case someone comes up with something against the oldest possible supported enterprise major.

@blizzz those images are still provided just the recipes are removed from master branch.

Sure, but it'll be uncomfortable to update or change any of them. It does not hurt having them lying around a little longer. It's unlikely, yet there is not pressing need to remove them early, or is there?

Fixed

@blizzz Ok reverted all php7.1 and 7.2
