tests: Remove unused testing code

Remove unused testing code.

Rationale:

Less is more :-)
Unused code is by definition “untested”

When has this last been used? Not sure if we want to remove library functions that are still used in other branches. Same for the key.py changes.

Last use was removed in b9f34e84befa7db6ff8c9b92a09d0dfa40388fb7

When was the first and last use? Might want to remove altogether after investigating that.

Last use was removed in your commit fac3e22b18cd29053bc17065fd75db7b84ba6f40 :-)

So please remove the constants here as well.

That was suggested by @MarcoFalke in #14312 (review) :-)

nit, unrelated.

Concept ACK, agree with rationale.

Mind sharing how you find these unused code?

@promag vulture is a great tool for finding dead Python code. See #14365 for vulture integration in Travis :-)

Closing this PR in favour of #14365 as suggested by @promag :-)
