Another round of CI bugfixes

Bugfix for exit codes for CI

Added support for CI by adding support for Environment variables.
This way you don't have to create a global configuration file on your CI deployment instance.

* Added support for Zappa
* Added support for custom project hook.
Create a folder `hooks` in your `.pete` project folder. Add a Python file based on the `tpd_pete.ihook.IHook`
* Added support to execute multiple deployment actions.
With one deploy command, you can now run CloudFormation, Zappa and Amplify.
* Changed CloudFormation deployment to no longer use AWS Cli, but instead use Boto3.

- Added AWS Amplify support
