Support Nginx and php-fpm

[apolopena]

Problem this feature will solve

Nginx server is very popular and Gitpod has it outof the box, however this starter does not support it out of the box.

Background

Proposed Solution

Add Nginx into the system which includes:

1. Aliases to start and stop it
2. mutitail and tail log monitor option in .starter.ini`
3. debug on and debug off implmentation
4. default server and start server functionality
5. expose port in .gitpod.yml

Constraints and Assumptions

• support Nginx as a default server type
  • implement into starter.ini and bash/helpers.sh
  • add an alias to stop and start it
  • wire Nginx into snippets/server-functions
  • wire Nginx into snippets/browser-functions

Alternatives or Workarounds

Use it by hand which would require editing `gitpod.yaml' on every new workspace creation, klunky

Additional context

Test it with all features like phpmyadmin

[apolopena]

Requires PHP-FPM which will slow down the workspace image build and add even more complexity to the conditional setup.

A few apis were added and I will finish with that but until PHP-FPM is implmented, php files will download instead of be displayed when served by nginx

I got nginx working with php-fpm7.4 and will implement it in this project. It does not slow down the workspace build like I thuoght it would so all good there. Check out a minimal working example here
