Publish version 0.2.1.X (#18)

- fix pester test execution order in vscode test task.
- fix coveralls.io link in bagde.
- skip coverage report creation for PR triggered builds
- update docs
- Connection type SCP added for `Connect-To` and `Disconnect-From`.

## Internal Changes
- pester tests now don't need to dotsource other public functions from the same module (fixes #17 )
  - helper and private functions stilll needs to be dotsourced.
- basic module tests added
- pester tests for `Resolve-Dependency` added
- Wrapper function  `Get-ModuleBase` added. This enables mocking in tests.
