Correctly fix aliases quoting logic (#206)

We were previously incorrectly adding double quotes for the alias values.
According to the man page it's not required. However, there is a requirement if
its a command being pipe.

In addition, the man page mentions this for the alias name:

  The  name  is  a  local  address (no domain part).  Use double quotes when the
  name contains any special characters such as whitespace, `#', `:', or `@'. The
  name is folded to lowercase, in order to make database lookups case
  insensitive.

This includes logic to support this automatically.

- Add new tests for aliases testing all types
- Convert all serverspec tests to inspec
- Add Github actions
- Update platforms to test
