Pull request description:

  Rather than using 3 different ways to build/format strings (sometimes all in the same test, i.e [`feature_config_args.py`](https://github.com/bitcoin/bitcoin/blob/master/test/functional/feature_config_args.py)), consolidate to using [f-strings (3.6+)](https://docs.python.org/3/reference/lexical_analysis.html#f-strings), which are generally more concise / readable, as well as more performant than existing methods.

  This deals with the `feature_*.py`, `interface_*.py` and `mining_*.py` tests.

  See also: [PEP 498](https://www.python.org/dev/peps/pep-0498/)
