Slim versions of TFX Docker images

[axeltidemann]

Could we have Docker images that are slimmer? Some examples of TFX Docker image sizes (compressed, even):

TFX 1.0: 5.67GB
TFX 1.5: 6.65GB
TFX 1.10: 8.53GB
TFX 1.15: 11.4GB

At least an explanation why the image sizes keep on growing would be great.

Or is the recommended way to build a Docker image yourself off a slim Python or Ubuntu image?

If that TFX image is based on the latest (1.16dev) image, then that is quite a saving, almost half. Interesting. Did you find it hard to build, @pritamdodeja ?

And: justbeambieber is for sure the funniest name I've seen for a Docker image, ever!
