[Bioc-devel] Weekly update of "bioconductor_docker:devel" docker image

[Turaga, Nitesh]

Hello Community, 

A brief update on the "bioconductor/bioconductor_docker:devel" image which is produced by the Bioconductor team.

The image will now be updated "weekly" on Friday evening around 6pm EST. This means that the image will have the latest version of R-devel by the week, and pushed to docker hub with a new version number located in the Dockerfile. 

The version number will be located in the LABEL field of the Dockerfile, which is available to be inspected in the docker image, with the following command 

```
$ docker inspect bioconductor/bioconductor_docker:devel
```

This will produce a JSON file which shows the following "Labels". Please note that the "version" in this section refers to the update, i.e "3.11.3". Next week it will be "3.11.4" and so on, till there is a new Bioconductor devel version number, which will reset the count. The version number in the format "x.y.z", refers to the bioconductor version number in the "x.y" coordinates, and the "z" coordinate indicates the version of the Dockerfile / Docker image being updated. 


```
            "Labels": {
                "description": "Bioconductor docker image with system dependencies to install most packages.",
                "license": "Artistic-2.0",
                "maintainer": "maintainer using bioconductor.org",
                "name": "bioconductor/bioconductor_docker",
                "org.label-schema.license": "GPL-2.0",
                "org.label-schema.vcs-url": "https://github.com/rocker-org/rocker-versioned",
                "org.label-schema.vendor": "Rocker Project",
                "url": "https://github.com/Bioconductor/bioconductor_docker",
                "vendor": "Bioconductor Project",

            }
```
