DataSourceAzure: update password for defuser if exists (#671)

cc_set_password will only update the password for the default user if
cfg['password'] is set. The existing code of datasource Azure will fail
to update the default user's password because it does not set that
metadata. If the default user doesn't exist in the image, the current
code works fine because the password is set during user create and
not in cc_set_password
