fix: enable self updating CLI

[wtrocki]

Add ability for CLI to self update itself. This requires more testing with actual release builds and general improvements

This PR will only work for latest release with manual darwin binary.
We need fix upstream: rhysd/go-github-selfupdate#48

Verification

0. change version in the makefile to 0.1.0
1. Run make binary
2. Run rhoas kafka list -v
3. Press y :D
4. CLI should be updated.
5. Execute command again (you should not see any message as CLI have been updated to latest)

Putting binary into system folder would fail and will require sudo to update

Verified after updating golang version in local

I think we need to test this version over the different machines/operating systems.

@rkpattnaik780 do you mind creating alpha release with this version so we can test it end to end on platforms like windows, mac and linux?

On it!

We will need to bump version in release workflow to 1.18x in order to create an alpha release.

Done little bit testing on the windows and mac. All seems to be working fine but additional changes are needed to inform user about update and add note that we need sudo if cli is located in folder that user cannot have write permission.

[wtrocki]

Updated version now asks users for permission and also mention that root is required.

[wtrocki@graphapi app-services-cli (self-updater ✗)]$ rhoas status
? New version of the RHOAS CLI detected. 
Do you want CLI to be updated to the latest version now?  

NOTE: You might need to run the CLI as root to make sure that binary file can be updated.
 Yes
RHOAS CLI updated to version 0.39.1
