[ISSUE]: Replace the custom ILog implementation with the standard Microsoft.Extensions.Logging.Abstractions with Serilog

[arturcic]

The idea is to have the custom ILog interface and it's implementations replaced with the standard dotnet packages, that will help us use the source generators.

Requiremens:

• The tests should be updated if necessary and they should remain green.
• Remove the old implementation including extensions
• Use Serilog for console and file sinks
• The logging level should be configurable from commandline using the existing flags
