new: [mongo] switch to pre-built images with upgrade directory

@@ -9,19 +9,58 @@ Since 4.0.6 based on alpine 3.9, alpine is not packaging mongo
 anymore. So we use the official version (that is huge). We still
 must change entrypoint to enforce proper directory paths.

+*** Build new images
 
-You can fetch latest official tags:
-#+begin_quote
-docker-tags-fetch mongo -l 10 -f '^[0-9]+\.[0-9]+\.[0-9]+$'

+Get the last upstream images versions with:

-#+begin_quote
-docker build . -t docker.0k.io/mongo:"$TAG"-myc
