Sudipta Biswas 54ea36a507 Fix to throw correct error code for bad attribute
Currently the neutron network API throws up error code 500 for
the extended attribute for segmentation id. This can be reproduced
if the user types in a random string in place of an integer value
for the segmentation id. The proper behavior should throw an error
code 400 with the appropriate failure message. This patch fixes the
same issue and covers it with a test case.
