Climate PID Autotune Logging fixes (#4136)
* pid autotune logging fixes * fixed clang-format request * improved and clarified logging * changed logging not to alter the TAG * logging now does not alter TAG. fixed clang formattting * fixed string issues * playing with strings to please the clang gods * playing with strings * Delete secrets.yaml * Delete console-fan-autotune-test.yaml * Update esphome/components/pid/pid_autotuner.cpp Co-authored-by: Jesse Hills <3060199+jesserockz@users.noreply.github.com> * Update esphome/components/pid/pid_autotuner.cpp Co-authored-by: Jesse Hills <3060199+jesserockz@users.noreply.github.com> * Update esphome/components/pid/pid_autotuner.cpp Co-authored-by: Jesse Hills <3060199+jesserockz@users.noreply.github.com> * Update esphome/components/pid/pid_autotuner.cpp Co-authored-by: Jesse Hills <3060199+jesserockz@users.noreply.github.com> * Update esphome/components/pid/pid_autotuner.cpp Co-authored-by: Jesse Hills <3060199+jesserockz@users.noreply.github.com> --------- Co-authored-by: Jesse Hills <3060199+jesserockz@users.noreply.github.com>
