Add continuous deployment (CD) automation for alchemiscale.org instance(s)?

[dotsdl]

A possible future state for us with the alchemiscale.org instances is that deployment of updated images to target hosts could be done via continuous deployment automation attached to this repository. Currently, built images must be manually deployed to instances of interest (e.g. prod, qa, dev).

Alternatively to this, it may also make sense to switch alchemiscale.org to using AWS EKS (managed kubernetes) for its instances instead, as updating images in-place from automation hosted here would be much simpler to do. This may prove less expensive than our current approach of using dedicated EC2 hosts, since we could collocate containers for multiple instances (prod, qa, dev) on a smaller number of hosts.
