Configuration / customization

Feature summary

The bitwarden cli supports to unblock with the given environment value or a password file: https://bitwarden.com/help/cli/#unlock-options. I want to have that available in the plugin.

Motivation / use case

It is kind of annoying to enter the master password every time after unlock the system, especially as a laptop user. By saving the password into the environment value or text file, it could largely improve the whole experience.

Proposed solution

I think we can then make it configurable in the plugin, by adding two fields:

1. passwordenv
2. passwordfile
   Either one of them is set, we will pass to the client instead of requiring the master password explicitly.
