feat(rust): Redesigned agama logs command to have functionality in th…

…e backend and accessible via HTTP API (#1720)

## Problem

Agama's CLI logs command used to be implemented with idea CLI running on
same machine as real installation (the backend). As this is not true
anymore and we have installer's backend and frontend separated with HTTP
API, which makes remote access possible, the logs command had to be
updated to support this idea.

[Its trello
card](https://trello.com/c/3A7vCwfS/3867-agama-cli-move-collecting-logs-into-backend-design-http-api-and-put-it-to-use-in-the-cli)

## Solution

- the particular code which is in control of collecting logs was moved
into agama-lib
- agama's web server has contains http(s)://<server_ip>/api/logs piece
in its public API
- agama's CLI uses the above API for downloading the logs

## Testing

- *Tested manually*
