/**
 * Handler sends logs to Telegram using Telegram Bot API.
 *
 * How to use:
 *  1) Create a Telegram bot with https://telegram.me/BotFather;
 *  2) Create a Telegram channel or a group where logs will be recorded;
 *  3) Add the created bot from step 1 to the created channel/group from step 2.
 *
 * In order to create an instance of TelegramBotHandler use
 *  1. The Telegram bot API key from step 1
 *  2. The channel name with the `@` prefix if you created a public channel (e.g. `@my_public_channel`),
 *     or the channel ID with the `-100` prefix if you created a private channel (e.g. `-1001234567890`),
 *     or the group ID from step 2 (e.g. `-1234567890`).
