Improve evohome exception handling and fix bugs (#22140)
* Use latest client library, evohomeclient v0.3.1 * Fix issue #22097: Failed to call service climate/turn_on... * BUGFIX: handle case where a Zone doesn't have a temperature * BUGFIX: missing exception handler, and inappropriate delint hints * Improve exception handling, and also better messages * improve code (REDACT secrets); remove TODOs * minor refactor - improve error message * more refactoring - improve error message * remove TODOs * update to latest evohomeclient library * Use latest client library, evohomeclient v0.3.1 * Fix issue #22097: Failed to call service climate/turn_on... * BUGFIX: handle case where a Zone doesn't have a temperature * BUGFIX: missing exception handler, and inappropriate delint hints * Improve exception handling, and also better messages * improve code (REDACT secrets); remove TODOs * minor refactor - improve error message * more refactoring - improve error message * remove TODOs * update to latest evohomeclient library * fix requests for houndci-bot * Tidy up requests exception handling * Correct lint error * update to latest client library * minor de-lint * more cleanup of exceptions, messages * refactored for new exception * fix error in requirements*_all.txt * de-lint * delint unused import * import 3rd-party library only inside methods * change honeywell tests * delint, fix typo * we dont log usernames, passwords, etc. * de-lintpull/22660/head
