Fix `RunAndListenClient`

Problem

RunAndListenClient: multiple goroutines across multiple runs of RunAndListenClient are reading from the “done” channel, and which one will receive something from that channel – completely random. As a result, in case of a lost connection, some random goroutine will exit and its graceful shutdown functionality will be lost.

---

Solution

To avoid such problems, the code should be simple. It’s hard to figure out how this method works because of multiple goroutines
and channels, thus it’s more error-prone. The easier the code, the harder a bug to find a place to hide. This functionality across all the methods and their goroutines can be done with a single context passed from the main. All the goroutines will read from ctx.Done() in select to shutdown gracefully.

Avoid the `env` file baked into the image

Problem

The env file is baked into the image. It’s an arguable topic, but here’s my other opinion: such an approach is ok when a configuration file changes the app’s logic, and the config itself is changed rarely. For example PostgreSQL config file. But the feed aggregator’s config is just URLs, IDs, credentials, and other dynamic data, which do not change app logic, and are changed pretty often. With the current approach, we have to build a new image on every change in configuration, which complicates the delivery workflow.
