Build gitpod.Dockerfile in terminal as if starting a workspace

[mteam88]

Is your feature request related to a problem? Please describe

When using Gitpod to develop my application, I am forced to restart the workspace on every edit to the .gitpod.Dockerfile or use the #imagebuild url trick. This takes a lot of time and the logs are not super accessible.

Describe the behaviour you'd like

In the Gitpod command prompt (Ctrl+Shift+P) a command could be like Gitpod: Build .gitpod.Dockerfile in terminal

Describe alternatives you've considered

This sequence here:
docker build -f .gitpod.Dockerfile -t gitpod-dockerfile-test .

docker run -it gitpod-dockerfile-test bash

Is sorta useful, and is essentially what I have been doing, but it does not completely simulate starting a workspace. My project (based on the workspace-vnc-full gitpod image) requires that. Rather annoying to start a whole new workspace. And recently I have had problems with that build system link to discord issue
