[keycloak-user] Get message for ModelException in admin-client

[Benjamin Hansmann [alphaApps]]

Is one able to get an error message from the resetPassword method of
admin-client if it somehow failed to reset the password, like when the
password is too short or does not comply with the password policy?

It throws an InternalServerErrorException in that case. On the server
side there seems to be a ModelException:
invalidPasswordMinLengthMessage. That information is lost...
