task/WG-121: migrate to database VM

[nathanfranklin]

Overview:

This PR migrates to database VM:

• removes db service/app and related DB volumes from kubernetes (i.e. all changes in kube/)
• adds files for geoapi-database (i.e. docker compose yml, postgress settings, readme, makefile which are all in devops/databae)

PR Status:

• Ready.

Notes:

I also put a top-level README in ~portal/ on geoapi-database VM:

portal@geoapi-database:~$ ls -l
total 12
-rw-rw-r--  1 portal portal  199 Aug 11 14:39 README.txt
drwxrwxr-x 10 portal portal 4096 Aug 11 14:39 geoapi

Tested locally - pinged db within container. LGTM!

@taoteg. fyi. in the services in kube that access the database, we have secrets/env-variables for database access. the previous secrets were stored under the name postgres in kube but @sophia-massie and I save the new ones under postgres-vm to not override the old ones. so we keep temporarily the old ones that work for the kube db and then also have the new ones that work for the new db vm.
