dashboard server upload

[jegesm]

It seems that if "--NotebookApp.base_url=$NB_URL" is set
then the dashboards bundler can't upload the files (use the api)
It is supposed to do something like this
"'http://dashboard-server/_api/notebooks/some'"
and does
"http://$project/notebook/gitlabadmin/07f159b4-99d4-47f9-9c91-d8654f3c70dc/api/bundlers/dashboards_server_upload/?notebook=gitlabadmin%2Fprojects%2Fgitlabadmin%2Freadmes%2FUntitled.ipynb"

It might be that the proxy needs to be configured
