* telegram_bot and notify.telegram enhancements:
- Receive callback queries and produce `telegram_callback` events.
- Custom reply_markup (keyboard or inline_keyboard) for every type of message (message, photo, location & document).
- `disable_notification`, `disable_web_page_preview`, `reply_to_message_id` and `parse_mode` optional keyword args.
- Line break between title and message fields: `'{}\n{}'.format(title, message)`
- Move Telegram notification services to `telegram_bot` component and forward service calls from the telegram notify service to the telegram component, so now the `notify.telegram` platform depends of `telegram_bot`, and there is no need for `api_key` in the notifier configuration. The notifier calls the new notification services of the bot component:
- telegram_bot/send_message
- telegram_bot/send_photo
- telegram_bot/send_document
- telegram_bot/send_location
- telegram_bot/edit_message
- telegram_bot/edit_caption
- telegram_bot/edit_replymarkup
- telegram_bot/answer_callback_query
- Added descriptions of the new notification services with a services.yaml file.
- CONFIG_SCHEMA instead of PLATFORM_SCHEMA for the `telegram_bot` component, so only one platform is allowed.
- Async component setup.
* telegram_bot and notify.telegram enhancements: change in requirements_all.txt.
