Too loose url regex for project/images/<instance-id>/create

[Lin Yang]

How to reproduce:
Input a wrong url http://<horizon>/project/images/<instance-id>/createabcd into browser, it shows the view of creating snapshot instead of 404 as expect.

Root cause:
The current url regex '^(?P<instance_id>[^/]+)/create' is too loose, which will match all url start with 'create'.

    Fix too loose url regex for snapshot creation

    Current regex '^(?P<instance_id>[^/]+)/create' for url
    projects/images/<instance-id>/create will match all urls start with 'create' by
    mistake. The '$' added will make sure the regex only match 'create' as expect.
