Rework Docker image (#5087)

Browse Source 
* fix #5086

* fixes #5082

- run tendermint init on runtime (if necessary)

* Address some feedback:

 - restrict the entrypoint to only run `tendermint`
 - script into /usr/local/bin

* make it also possible to run ``ith unmodified config again via:

`docker run -v $HOME/.tendermint:/tendermint tendermint/tendermint init

* Update DOCKER/docker-entrypoint.sh
