Add CI/CD pipeline

[carltibule]

The pipeline should build the back and front ends, run unit tests, and create separate docker images for both. If there's any failure at any step, send a Discord message to specified webhook.

Consider the following:

• Should a new project and network be created, with new VMs spun up, with properly configured access (IE: VPN access only). - - How should some services be publicly exposed?
• Should a special environment be spun up specifically for YABA? One consideration is Yes, but there would be 2 YABA prod environments: one for public access and one for self-hosting.
• Should new db containers be spun up or use existing one? One consideration is Yes, follow the setup as above

There will be 3 environments: prod, staging and dev. All will be publicly accessible on the same project as all of the other services running on iwanaga. DBs already setup for all of the environment

Might have to switch to using env for storing credentials, for easier dockerizing https://learn.microsoft.com/en-us/dotnet/core/extensions/configuration-providers#environment-variable-configuration-provider
