Add R kernel to docker image

[manjilasingh]

Users currently need to reinstall r kernel every time they start a server. Adding r kernel directly to the image would eliminate the need of repeated installations. The following line can be added to the Dockerfile:
RUN conda install -c r r-irkernel

@arpita0911patel might have that info

Correct command to use
RUN conda install -c r r-irkernel -y
After rebuild and use the image to launch instance in staging.

$ jupyter kernelspec list
[ListKernelSpecs] WARNING | Config option `kernel_spec_manager_class` not recognized by `ListKernelSpecs`.
Available kernels:
  python3    /srv/conda/envs/notebook/share/jupyter/kernels/python3
(notebook) jovyan@jupyter-benlee0423:~$ 

This means conda command is not compatible with Dockerfile, and the command does not install R kernel to the image built.

@arpita0911patel
We like to ask new image built tested by requester in staging if it works.
Can you share the email address who requested r kernel, and I will send instruction how to test in staging?
