Support a setting to disable certificate verification

[Kircheneer]

Environment

• Nautobot version: 1.3.3
• secrets version: 1.2.0

Proposed Functionality

Implement a setting to allow for disabling of certificate verification. There used to be a workaround on the requests side to set the environment variable CURL_CA_BUNDLE to an empty value, but this is no longer possible as of requests version 2.28.0.

Use Case

In testing environments or during buildout of new environments there might be the need to disable certificate verification because self signed certificates are used.

@Kircheneer Thanks for the submission. Some questions:

• Is this specific to a backend, or in general?
• And if it is specific to a backend, can this be passed through with a kwarg a la verify_ssl=False to the calling client?

[Kircheneer]

My question was mostly aiming for HC vault where you can pass verify=False to hvac.Client but I guess it could be something that's generally useful for all backends that can be deployed on-prem?

This happens to be part of my PR #35 as using vault locally in a kubernetes cluster you might have a self signed cert so I added the verify capability to the hashicorp provider in general not just for kubernetes.

Implemented for Vault in #35 as the ca_cert configuration parameter.
