Implements Minio setup and /save_resume functionality.

[iramykytyn]

🛠 Changes being made

• Adds /save_resume <link> command to Slack bot. Adds functionality to upload a resume as PDF file.

• Adds docker-compose to run S3 storage on 7000 and 7001 ports. Cloudflare tunnels configuration is also added to be able to access Minio dashboard and files through public domains. TOKEN_7000_PORT and TOKEN_7001_PORT have to be added to scripts/minio/.env file. Cloudflare can be excluded when running on the local machine.

  

• Adds S3StorageManager class which handles S3 storage connection and PDFs upload.

• Adds ResumeHandler class with functionality to download PDF's

• Updates bot to listen to pdf upload event and save it to S3 storage and return the link to the pdf in thread.

Known issues

• Currently, the logic with PDF upload doesn't work if more than 1 pdf is uploaded. It has to be fixed as a separate issue.
• TestResumeHandler is currently connecting to real S3 storage which is not a good practice. This should be changed to run minio in CI environment as a docker so test will connect on localhost.
