Migrated CI from Azure Pipelines to GitHub Actions.
Until the release process is figured out in Actions, we'll stick to using Azure pipelines for releases.
- Create `Config` struct that is added to `Context` when initialized
- Read `~/.confg/starship.toml` during initialization (can be updated later to also look at `$XDG_CONFIG_HOME`)
- `Context` now has a method for creating modules. This allows us to provide modules with a reference to the configuration specific to that module
- Create subcommands to be able to print modules independently
- `starship prompt` will print the full prompt
- `starship module <MODULE_NAME>` will print a specific module
e.g. `starship module python`
- Added `--path` flag to print the prompt or modules without being in a specific directory
- Added `--status` flag to provide the status of the last command, instead of requiring it as an argument
- Refactored integration tests to be end-to-end tests, since there was no way in integration tests to set the environment variables for a specific command, which was required for the `username` module
- Moved e2e tests to `tests/testsuite` to allow for a single binary to be built
- Tests will build/run faster
- No more false positives for unused functions
- Added tests for `username`
- Removed codecov + tarpaulin 😢
* Publish docker image used in testing
* Update integration_test to pull the image and build, using the image as its cache
* Publish the built image after successful test runs on master
