Adding support for custom tokens

[vsoch]

Signed-off-by: vsoch vsoch@users.noreply.github.com

Description of the Pull Request (PR):

This PR will be early work to address #154 - and the branch can be tested as follows. First, create a dummy dockerfile that uses this branch, e.g., I could run docker run -v $PWD:/data quay.io/vanessa/expfactory-builder build test-task and then just change the branch:

FROM quay.io/vanessa/expfactory-builder:base

LABEL EXPERIMENT_test-task /scif/apps/test-task
WORKDIR /scif/apps
RUN expfactory install https://github.com/expfactory-experiments/test-task

ENTRYPOINT ["/bin/bash", "/startscript.sh"]
EXPOSE 5000
EXPOSE 80

build it

$ docker build --no-cache -t experiment .
``
And then you can start it headless (or start it without detached and open another terminal to interact with it - up to you!)

```bash
docker run --name experiment -v $PWD/:/scif/data -d -p 80:80 experiment start

Now we can execute commands to interact with the install inside. E.g., list users

docker exec experiment expfactory users --list

there should be a command for --tokens so we can create a text file with line separated tokens (comments are okay)

# tokens.txt
# this is a comment
AAAAAA
BBBBBB

the present working directory is bound to /data so let's ask expfactory to add users from the tokens file there (from the container's point of view):

docker exec experiment expfactory users --tokens /scif/data/tokens.txt
2 users existing or generated from file.

You should then be able to see the data directories in expfactory in the PWD:

$ ls expfactory/
AAAAAA  BBBBBB

And also login via the interface with the tokens (I couldn't test this because I rigorously block cookies)! Also note a more complete variation of these instructions will be added to the expfactory.github.io docs, shown here
