Description [REQUIRED]

edgex-ui-go docker does not use multistage Docker build.

As a consequence, the edgex-ui-go container ships with go compiler tools and source code for the UI backend.

Describe the solution you'd like

Use multistage build and only copy runtime dependencies into the edgex-ui-go container.

Describe alternatives you've considered

Have you considered any alternative solutions or workarounds?
