CLOUDP-292660: add a new 'foascli sunset list' command to foascli to list all endpoints with theirs sunset date

[andreaangiolillo]

Proposed changes

CLOUDP-292660

This PR creates a new command foascli sunset list to list all the endpoints with their sunset date in an open API spec. This command will then be used to send us a notification when a new endpoint is approaching its sunset date

Testing

./bin/foascli sunset ls -s /Users/andrea.angiolillo/workspace/[redacted]/server/openapi/services/openapi-mms.json

I removed the paths and team name from the output

[
  {
    "http_method": "GET",
    "path": "/api/atlas/v2/groups/{groupId}/backup/**/{exportBucketId}",
    "version": "2023-01-01",
    "sunset_date": "2026-05-30",
    "team": "Backup - *****"
  },
  {
    "http_method": "DELETE",
    "path": "/api/atlas/v2/groups/{groupId}/***/{clusterName}",
    "version": "2023-01-01",
    "sunset_date": "2025-06-01",
    "team": "Atlas D****"
  },

Next Steps

I will create a GH action to send us a notification when an endpoint is approaching the sunset date
