Embed sdk versions (#68)

Part of https://github.com/pulumi/ci-mgmt/issues/915

Install pulumi in standard way 

Use the same method as other providers to install the pulumi CLI.
- Lock the version of the CLI and therefore codegen for consistent build
results.
- Ensure the local language plugins are using by disabling ambient
plugins.

Enable respect schema version

Remove setting version at SDK build time
