Zend stack and project sample (#2700)

### What does this PR do?

Adds a stack with [Zend Server](http://www.zend.com/en/products/zend_server), based on the [official docker image](https://hub.docker.com/r/_/php-zendserver/). Zend Server is a professional and certified PHP distribution. The docker image includes a free trial Developer license.

Also adds a project sample of the [Astro Splash](https://github.com/kaloyan-raev/AstroSplash) application, which is a demo app based on the [Zend Expressive](https://zendframework.github.io/zend-expressive/) framework.

After creating a workspace with these stack and template the user must:

1. Execute the `configure` command.
2. Execute the `restart zend server` command.
3. Click on the preview link generated by the `restart zend server` command.

### What issues does this PR fix or reference?

- PHP support #2590

### New behavior

- New stack with Zend Server.
- New project sample: Astro Splash demo app, based on Zend Expressive.
