Collect the env variables when you are ready to migrate to Vaultik

[tomiok]

Is your feature request related to a problem? Please describe.
You are not using Vaultik. You found it in Github. You are using env variables.
Now you want to migrate and start using Vaultik, that's good! so you can share all the env variables that you want to
migrate in 2 formats, passing a file in csv or via CLI, passing all the values.

The result should be with all the envvars now saved as a REAL secret.

Describe the solution you'd like

• Introduce a new command with a flag to see if we are using a file or the values
• parse de file | parse de values
• Find all the env variables, ignore if something is empty
• save as secrets
• print a message with how many secrets are created
