Logstash support for logs

[MatthewZMSU]

Description

As some companies use ELK-stack for storing logs we propose Logstash support for the service.
Added new modules in order to add the feature and also commented several important functions.

New dependencies:

• Winston-Logstash

Type of change

• New feature (non-breaking change which adds functionality).
• This change requires a documentation update.

How Has This Been Tested?

I raised my own ELK-stack up using docker-compose. It worked well.

As I have shown in the checklist I haven't changed our README.md file. I think we need to add information about environment variables we use.
What do you think?
