Sorry, ignore me.  I didn't read enough to see this is only plumbing
our current environment variable method into the new store open API we
use for providers which didn't pick up a password method.  However, the
thought does occur: if the pkcs11 engine does this by an engine
parameter, wouldn't the provider have an equivalent provider parameter?
