[DH-66] move conda and R install locations, fix popcon deployment path, install temp version of popcon

[shaneknapp]

https://jira-secure.berkeley.edu/browse/DH-66

repo2docker is installing python to /srv/conda, and these Dockerfile-based images are deploying to /opt/conda.

since the majority of our deployments are following the repo2docker paradigm, let's update these hubs to do the same.

we will also be moving the popcon ipython startup script to /srv/conda/... so that it's in the proper ipython search paths.

re builds failing:

W: Failed to fetch https://cloud.r-project.org/bin/linux/ubuntu/focal-cran40/InRelease  Could not resolve 'cloud.r-project.org'

cloud.r-project.org is unreachable, as is r-project.org :(

This will help. A simpler way would be to set the popcon path to be under /etc/ipython which every ipython reads. But aligning our dockerfile builds with the others helps to avoid future surprises.

plan A was to stick the popcon script in /etc but after a few minutes of thought i decided that normalizing installation locations was more bueno than not.

actually, you're right and /etc/ipython is the right place for the startup script to live.

I think both changes will be helpful!

btw we're blocked on yuvipanda/python-popularity-contest#3 for data101 and stat159 hubs (both have ipydatagrid installed).

welp this has been a bunch of work but i think we're good to go!

i'm actually just using the git resolver for pip to get around this for now... it doesn't work on a couple of hubs for random reasons but (thankfully) none of them have the ipydatagrid package installed.
