invalid URLs are not suppressed When use openstack endpoint create

[jiaxi]

When creating endpoint with the command line below:
openstack --debug endpoint create nova public " http://127.0.0.1:8774 /v1.1/\$(tenant_i d)s"

Create endpoint successfully with invalid url.Obviously It should be suppressed as bug #1471034 said. it's implemented by the Identity v3.0 API.

This bug is different from bug #1471034, because bug #1471034 produced by keystone endpoint-create.It's implemented by
the Identity v2.0 API.

The Keystone command line interface packaged in python-keystoneclient only supports the Identity v2.0 API.
The OpenStack common command line interface packaged in python-openstackclient supports both v2.0 and v3 APIs.

So I modify the Identity v2.0 API can resolve bug #1471034. Review: https://review.openstack.org/#/c/200512/

I want to solved the url validation problem with two seperate git review.
Because this can be more effectively and easier to be done.

I think this is actually a duplicate. Both changes describe the same broken server behavior.

@David Stanek (dstanek):
Could I modify Identity V3 api in another commit?

Sure, but I think you can probably just use the same commit since the validation logic should be shared.

Also, the openstack client can use v2.0. It's actually just a wrapper about keystone client.
