IaC: Service for creating and uploading calibnet snapshots

[lemmih]

Summary of changes Changes introduced in this pull request:

• Add script for initializing a service that automatically uploads calibnet snapshots to Digital Ocean and reports failures to slack.
• Decided not to use terraform due to the complexity.
• The infrastructure consists of a single boot script that is run on a server with docker installed. The bootscript takes care of all other dependencies and automatically updates itself via watchtower.

Random idea, it'd be useful to store the checksum as well (like for mainnet snapshots on AWS). Random file corruption occurred when I tried to upload large files into DO Spaces, so it'd be nice to have some checks.
