Fixed aperturectl apply when controller address is provided (1966)
Description of change
There was an issue where even if we provide `--controller` flag, it was
trying to connect to kubernetes.
Also, added support for insecure controller communication.
Also, --kube flag is now default for all subcommands and can be omitted.
**New Feature:**
- Added support for insecure controller communication and skipping TLS
certificate verification
**Bug fix:**
- Fixed issue where `--controller` flag was not being used to connect to
the controller
- Made `--kube` flag default for all subcommands, allowing it to be
omitted
**Documentation:**
- Updated documentation to reflect changes in code and new features
> 🎉 A flag once lost, now found and secure,
> Insecure connections, we can endure.
> With kube as default, our commands are free,
> Documentation updated, a joyous decree! 🥳

> Scaling with grace, as our codebase is impacted. 🌟
