    Refactor Dockerfile to use multi-stage builds (#2004) (#2051)
    
    Refactored Dockerfile to use multi-stage builds for reduction image size.
    
    The installation of the packages required for the build and the build 
process are carried out at the build stage. The built binaries are then placed 
in the final image.
    
    This changes has reduces the image size about 1/3.
    ```
    $ docker image ls apache/age
    REPOSITORY   TAG       IMAGE ID       CREATED          SIZE
    apache/age   tmp       5ffd0b539a88   22 minutes ago   458MB <-- New image
    apache/age   latest    fb44b5789198   2 months ago     1.5GB <-- Original 
image
    ```
