[gitpod] Starting and stopping apache and php dev server

[apolopena]

Problem this feature will solve

Starting and stopping apache is hassle. Commands are a too long to type and memorize when swapping between web servers. Also its not clear when the apache server is stopped because the multitail that was spawned for it does not close.

Background

The user may need to swap between webservers (php built-in webserver, apache2 etc.). These webservers may also need to be run in parallel or all stopped at once.

Proposed Solution

Add an functions in .bashrc from `.gitpod.Dockerfile

1. Start apache2 with multitail for apache2 log and error log
2. Stop apache2 and the multitail that was spawned for it.
3. Start the PHP dev server
4. Stop the PHP dev server

Constraints and Assumptions

Add functions to .bashrc from `.gitpod.Dockerfile

Alternatives or Workarounds

None worth mentioning

Additional context

This will setup a new system of writing functions to .bashrc from the bash/snippets/ directory
