Send inventory and heartbeat to temporary endpoint

[gsanchietti]

Proposed Feature

Add a temporary change to the existing send-inventory/send-heartbeat client scripts so they also POST the inventory and heartbeat in the new "phonehome" format to the migration proxy endpoints on the current my server:

• POST https://my.nethesis.it/proxy/inventory
• POST https://my.nethesis.it/proxy/heartbeat

This request should be executed only for enterprise machines and must use the same system credentials (LK / secret) so existing systems do not need to recreate credentials.

Purpose and Motivation

Why:

• We need to automate the migration of reseller systems to the new my service without forcing systems to recreate LK and secrets.
• Doing this temporarily from the clients ensures inventories/heartbeats reach the new my via the proxy and lets us maintain a mapping of old->new system IDs during the migration.

Importance:

• Minimizes manual work and disruptions for resellers and endpoints.
• Enables realistic load/functional testing of the new inventory engine.
• Allows a staged migration while preserving credentials and continuity.

Proposed Solution

Modify the existing client scripts that send inventory and heartbeat (the current send-inventory scripts) to perform an additional POST to the migration proxy endpoints in the new "phonehome" format. Key points:

Behavior:

• Keep existing behaviour (no breaking changes).
• After the current inventory/heartbeat send, duplicate the request to the proxy endpoints:
  • POST https://my.nethesis.it/proxy/inventory
    • Content-Type: application/json
    • Basic auth: -u "SYSTEM_KEY:SYSTEM_SECRET"
    • Body: inventory in the new phonehome JSON format (e.g., @inventory.json)
  • POST https://my.nethesis.it/proxy/heartbeat
    • Basic auth: -u "SYSTEM_KEY:SYSTEM_SECRET"
    • Body: empty

Only send these additional requests for systems detected as "enterprise".

Also send the following info under the facts field:

• fqdn: "host.firewall.net",
• default_ipv4: "1.2.3.4",
• default_ipv6: "2a03:b0c0:3:f0:0:1:dbfe:3000",
• kernel_version: "5.14.0-284.11.1.el9_2.x86_64",
• uptime_seconds: 29966,
• timezone: "UTC",
• package_updates_available: true
• image_updates_available: false

If the same info must be sent also for community, make sure data are anonymized.

Additional Context

Only enterprise machines should send the extra requests. This is a temporary measure until the migration completes and systems are fully associated to organizations on the new my.

Example curl commands for the proxy endpoints (for reference):

Heartbeat:

curl -X POST https://my.nethesis.it/proxy/heartbeat \
  -u "SYSTEM_KEY:SYSTEM_SECRET"

Inventory (phonehome JSON):

curl -X POST https://my.nethesis.it/proxy/inventory \
  -H "Content-Type: application/json" \
  -u "SYSTEM_KEY:SYSTEM_SECRET" \
  -d @inventory.json
