Implement microprofile health style endpoint for CDA monitoring #1628
Description
Is your feature request related to a problem? Please describe.
CDA itself is getting more complex with additional backends.
Additional there is need for more reporting about what is support so that clients can fail and expand gracefully.
Describe the solution you'd like
Similar to opendcs/opendcs@2f0166e, make use of the jakarta ee microprofile health design to implement both simple and detailed state handling.
Describe alternatives you've considered
Build something that doesn't have a defined standard?
Additional context
Currently we report state with just checking the offices endpoint (it's fast and proves the database is alive), however the micro profile health includes startup, liveness, and ready which can be useful to understand what state the system is in.
