Allow deployment with a single hostname

[amrc-benmorrow]

The requirement for wildcard hostnames and TLS certificates is causing problems. We should see if we can eliminate it, at least as an option. Possibilities are:

• Using paths below the root URL, e.g. https://my.fp/configdb. The F+ services are supposed to support this, though I don't know if all the ServiceClient libraries implement it correctly. I don't know if third-party components like Grafana will support it.
• Using ports. This would be crude, and would definitely require links (at minimum) from the new Admin interface.

Possibly a combination of the two might be needed.

This would be of interest for us with RR SMR, as it would allow access to the grafana dashboards without having to edit the hosts file of devices. Which is undesirable and even in the case of iPads impossible.

Users Story

End user should be able to access their data dashboards from a simple link on an unmodified device. Thus QR or other markers could be scanned in around the site to bring up relevant dashboards.
