deploy cellxgene in kubernetes

[inodb]

Previously we have been able to deploy instances of cellxgene in heroku. See e.g.:

https://github.com/cBioPortal/brugge-singlecell

It alows one to point to an h5ad file in a bucket and deploy it. It would be great if we could deploy more cellxgene datasets on the cbioportal domain like e.g. *.cellxgene.cbioportal.org using our k8s infrastructure (or Fargate or some other AWS option, whichever makes sense). There is also this extension that allows one to use multiple datasets:

https://github.com/Novartis/cellxgene-gateway/tree/master

Using the cBioPortal domain would in addition allow mounting the tab inside of cBioPortal (this doesn't work atm because CORS is disabled on https://cellxgene.cziscience.com/)

Previously Jessica Singh from the Hyve used it and demo'ed its use. We've also had a server set up at single-cell.cbioportal.org but it is currently broken. We thought using the K8s infra or some other set up with auto ssl and all the bells and whistles might help with maintainability
