Node-jsonwebtoken: Missing documentation for expiresInMinutes and expiresInSeconds

[samholmes]

Documentation should explain what possible values are valid for these options. Should the expiresInMinutes be the number of minutes from unix time or number of minutes from token generation?

[Zertz]

The name implies it is from token generation: [token] expires in x minutes

[jfromaniello]

Yes, it is from token generation and I don't like these parameters.

[knownasilya]

Please make it only one option. As a library author it's a big pain when exposing the config to users because it's confusing which one will have effect.. One option should be enough.

[jfromaniello]

These parameters are deprecated and will be removed on next major version.

[alexilyaev]

For those who stumble upon this, we should use expiresIn from this point on.
