Ability to access 1Password secret in HTTP Client

[bric3]

In IntelliJ Ultimate there's an HTTP client, the client has a concept of private environment file, where one can put secret(s) that will be used by the HTTP Client.

This would be very practical to not store secrets in this file, but to actual fetch them from 1Password.

E.g. assuming the command to get the secret would be op item get "finnhub" --fields "token".

But yet again IntelliJ SDK has to provide the necessary facilities to make this possible.
