Recognize Sindri (auth) config file

[katiemckeon]

🌟 Feature Request

📝 Description

Sindri's rust SDK and rust CLI analogue should strive to mimic the same auth patterns as the preexisting sindri-js & CLI. Primarily, the config files created by the CLI here should cross over to any rust application and the cargo sindri CLI should provide a similar login experience that plays nicely with any login details saved by the sindri-js CLI.

🤔 Rationale

Users switching between languages don't need to worry about logging in again or learning a new auth pattern.
