Support serving of backend translations (#12453)

* Add view to support backend translation fetching * Load backend translations from component json * Translations for season sensor * Scripts to merge and unpack Lokalise translations * Fix copy paste error * Serve post-lokalise translations to frontend * Linting * Auto-deploy translations with Travis * Commit post-lokalise translation files * Split logic into more helper functions * Fall back to English for missing keys * Move local translation copies to `.translations` * Linting * Initial tests * Remove unnecessary file check * Convert translation helper to async/await * Convert translation helper tests to async/await * Use set subtraction to find missing_components * load_translation_files use component->file mapping * Remove duplicated resources fetching Get to take advantage of the slick Python 3.5 dict merging here. * Switch to live project ID
