Support multiple accounts

[Mikescops]

Supporting multiple accounts will allow to query the vault and other commands in the event you have different accounts (ie: personal and professional).

• ability to login with an extra account
• ability to define an account to run a given command (this will force the login selector with --account)
• ability to select the default account to run commands
• ability to logout from one account (only reset related resources for this account and de-register the device)

Hi, I'm interested in contributing to this issue. I'd love to discuss potential approaches and gather feedback from the community before I start. Looking forward to your thoughts.

Hey @Marciustech, thanks for your interest, I'm currently working on a refactor for the auth part so I think it's not the best timing to work on multi account.

But after that it will be pretty easy to have multiple accounts as everything is already well split in the database so we can query only transactions and secrets for a specific account.
