Allowing k8s connection using self signed certificate

### Is your feature request related to a problem? Please describe.
I have multiple clusters that uses a private chain and kubevious is unable to connect on them, printing this error:

### Describe the solution you'd like
Passing and env variable or some other tips at runtime to configure kubevious to not verify endpoint certificate.

Start by locating the Kubernetes connection setup and runtime configuration entry point; the issue names no file or test. Reproduce the reported private-chain failure and verify that a runtime option lets the connection proceed with certificate verification disabled.
