Error message is malformed when removing a non-existent security group from an instance

[Phil Day]

Trying to remove a security group from an instance which is not actually associated with the instance produces the following:

---
$nova remove-secgroup 71069945-5bea-4d53-b6ab-9026bfeebba4 phil

ERROR: [u'Security group %(security_group_name)s not assocaited with the instance %(instance)s', {u'instance': u'71069945-5bea-4d53-b6ab-9026bfeebba4', u'security_group_name': u'phil'}] (HTTP 404) (Request-ID: req-a334b53d-e7cc-482c-9f1f-7bc61b8367e0)

---

The variables are not being populated correctly, and there is a typo: " assocaited"

    Error message is malformed when removing a sec group from an instance

    In the current code the Error message string for a security group which is not
    associated with an instance does not get expanded correctly, resulting in users
    getting a message:

    ERROR: [u'Security group %(security_group_name)s not assocaited with the
    instance %(instance)s', {u'instance': u'71069945-5bea-4d53-b6ab-9026bfeebba4',
    u'security_group_name': u'phil'}]

    In addition fix a minor typo in this message, and clean up a few cases where
    error messages are not being passed through _() for i18n.
