* Breaking change: Rewrite opentherm_gw to add support for more than one OpenTherm Gateway. Breaks config layout and child entity ids and adds a required parameter to all service calls (gateway_id). * Add schema and parameter description for service opentherm_gw.reset_gateway. * Add optional name attribute in config to be used for friendly names. Fix bugs in binary_sensor and climate platforms. * pylint fixes * Remove unused variables. * Update manifest.json, remove REQUIREMENTS from .py file * Update CODEOWNERS * Address issues that were brought up (requested changes): - Move imports to module level - Change certain functions from async to sync - Move constants to const.py (new file) - Call gateway setup from outside of __init__() - Move validation of monitored_variables to config schema * Address requested changes: - Make module imports relative - Move more functions from async to sync, decorate with @callback where necessary - Remove monitored_variables option, add all sensors by default
