add global option to disable TLS validation #755
Description
What would you like to be added
Add a (global) flag to disable TLS validation for OCM-CLI's commands. Inspired by curl, the flag might be named --insecure, but any name will do.
Why is this needed
For development purposes, there may be cases where no valid certificate is available in a testing environment (e.g. if using a self-signed certificate). Having the option to disable TLS validation will be handy in such cases.
One might also consider productive scenarios, where, through a misconfiguration, TLS validation fails, and OCM-CLI is needed to perform urgent tasks that would otherwise be blocked by TLS validation issues.
Admittedly, those are exceptional and corner-cases. However, most other tooling supports explicit disabling of TLS validation, including e.g. package-managers (apt, apk, pacman), HTTP-APIs for all programming languages, HTTP-tools, such as curl or wget, ... - even security-aware tools such as ssh offer disabling of checks / unsafe mode of operation.
