Investigate and document strategies to debug cloud gateway outages or potential misconfiguration of Command Centre

[devraj]

Describe the bug
This initially came from me noticing that my CI pipeline had failed to run. I have been making a fair bit of changes to my command centre configuration (pending documentation) to get my 7000 demo controller working over a WAN.

This lead me to believe that I had misconfigured the Command Centre for it to stop responding to the connections from the Cloud gateway.

Upon running the tests locally I found that all of our tests were failing and hence investigated to find that there were connection timeouts. These are likely caused by:

• Misconfiguration of the Command Centre
• Outage of the Cloud gateway

This ticket is to mainly document strategies to debug what may be a configuration issue and what otherwise might be an outage.

We also found that there were some unexpected behaviours with CardholderDetail no longer validating. This could well be due to a pyndatic update, which should be checked out.

E pydantic_core._pydantic_core.ValidationError: 1 validation error for CardholderDetail

To Reproduce
Steps to reproduce the behavior:

1. run task test
   2 Expect to see Connection failures
