❇️ feat: Support OKS_PROFILE environment variable

[emmanuel-quevillon-outscale]

User can set OKS_PROFILE environment variable as default profile when running any oks-cli command without the need to set --profile option

Dynamic shell completion no longer works after these changes.
Please refer to the shell_completions function in the utils.py file.
It need to be updated to reflect the recent changes.

Looks good for me.
Just one point should be added into docs:
To use autocompletion with environment-based profiles, you must
export OKS_PROFILE= before running the CLI.
Inline assignments like OKS_PROFILE=ppd oks-cli ... will not be available
to the completion engine due to shell behavior.

I agree, should this be added into the README.md file or in the OUTSCALE offical documentation?
