Az CLI ignores options if environment variables are set

[manekinekko]

Describe the bug

When creating a storage instance, the az CLI will check if the following environment variables are set, if so, it will use them and ignore the options passed to the CLI:

• AZURE_STORAGE_CONNECTION_STRING
• AZURE_STORAGE_ACCOUNT
• AZURE_STORAGE_ACCESS_KEY

To Reproduce

Set any of these environment variables in your terminal before usign hexa:

AZURE_STORAGE_ACCOUNT="fake" hexa init --just=storage

Expected behavior

Hexa (and the az cli) should ignore the user-defined env variables and use the values passed through the CLI options.

Additional context

Other Azure services might be affected by a similar bug (needs to investigate).
