(MODULES-10800) Add GitHub Actions workflows

Added GitHub Actions workflows for `Static Code Analysis` and `Unit
Tests` that run each time there is a new `pull request` or `git push`.
`Unit tests` are also set to run every workday at `05:00:00 UTC`.

The `.yaml` config files of `Travis` and `AppVeyor` have been removed.
