Add ingest.sh script.

[pantierra]

Data Management (data ingestion in a first step) is a common requirement for several of our eoapi-k8s deployments and projects.

From my perspective we should think about data on eoAPI as "content" and not so much as "configuration". While configuration should be in code and part of the reproducible deployment, content should me managable by an admin user. At some point we probably want to think about building some auth-supported API to allow management, eventually even connecting it to some user interface.

This PR consists in a first simple step to add very basic ingestion as a bash script ingest.sh and the related make ingest command, it:

• looks for a kubernetes the eoAPI raster pod in the namespaces eoapi and default
• it installs pypgstac on it
• it uploads collection.json and items.json from the current directory (can be overridden with the environment variables EOAPI_COLLECTIONS_FILE and EOAPI_ITEMS_FILE.
• it pypgstac loads the collection and items into the pySTAC postgresql database.

I've explored this topic further, and it seems that the most effective way to implement an API is by using the stac-fastapi-pgstac endpoints that support the STAC API Transactions extension. Currently, securing these endpoints is a challenge, with most people resorting to either an API Gateway or developing a custom version of stac-fastapi-pgstac. We might want to consider enhancing stac-fastapi-pgstac to include this functionality, potentially leveraging the STAC API Authentication extension.

In the meantime, the ingest.sh script and command will simplify the ingestion process.

I will leave running the script to others.

It looks nicely laid out and documented and is providing at least a basic mechanism for data ingestion, which is a battery we have to include, IMO.

Overall looks great to me, a real step in to making this easier

Just a few comments that I think will waterproof this

LGTM!
