Hello,

It's possible to add the context in the PasswordAuthorizationHandler method ?

Current signature:

PasswordAuthorizationHandler func(username, password string) (userID string, err error)

Propose one:

PasswordAuthorizationHandler func(ctx context.Context, username, password string) (userID string, err error)

It's quite usefull to follow request id or tracing.

I'd be glad to propose you a PR.
