Fix a issue on retrieving default quota in Create Project

quota names for security group are different between nova and neutron,
so the same appoach can be used for floating IP. This commit reverts
the change in get_default_quota_data in commit c44552fe66 and changes
get_disabled_quotas to determine security group and rules quotas come
from nova or neutron.

Show an error message on instance launch error

Since instance creation happens asynchronously, all that currently
happens on the Horizon side is the state changes from Creating to Error.

This change checks the instance state during the Ajax request on the
backend and returns an Ajax error message popup if the status is
'ERROR'.
