Migrating to GH actions

[mariotoffia]

Today it uses appveyor to build and perform unit testing. This needs to be migrated to github.

• Build
• Ensure that test may access docker command on the path to spin up containers
• Run test -> Spins up many docker containers, configures docker networks, and test volume handling
• Publishes the nuget packages to nuget.org - API key needs to be a secret (as it is in appveyor)

This should be migrated into github workflows. Only build and test on pull request merge attempt to master and not for each commit.
