Update middleware that was moved to keystonemiddleware

S3Token middleware has been moved (and slated for removal) in the
Juno Release. This Middleware has been removed from Keystone.

Keystone now uses the middleware located in keystonemiddleware for
providing the code for ec2_token middleware. The middleware class
in Keystone has been deprecated and is slated for removal in the
L release.

auth tests should not require admin token

Currently all the v3 auth tests are calling self.post(), which
eventually going through keystone.tests.test_v3.v3_request().
The v3_request method always requires an auth token by default.
But since V3 auth token API is an unprotected API, there's no need
for an auth token in order to make the request.

Adding support for ldap connection pooling.

Using ldappool library to establish connection pooling.
Connection pooling is disabled by default.
Pooling specific configuration parameters are added in ldap section.
Added pool test using existing FakeLdap as connector class.
Added pool specific ldap live test. These tests are executed similar to
existing ldap live test.
Addressed async search_s and result3 API issues mentioned in review.
Added separate connection pool for end user auth bind done by keystone
identity ldap driver logic to avoid saturation of pool by these kind of
binds and limiting pool effectiveness for other ldap operations.
Rebased with lastest master and addressed doc comments.

Move token persistence classes to token.persistence module

Create and move all token persistence code to a new token.persistence
module. This allows the token_provider_api to utilize the token
persistence service without introducing circular dependencies. A proxy
class, that will log a deprecation message if instantiated, has been
created for both the token.core.Manager object and token.core.Driver
object. These proxy objects are slated for removal in the K cycle.

remove static files from docs

Since we are already using oslosphinx, there is no reason to

add internal delete notification for endpoint

I think endpoint is not an important resource which other projects would
pay close attention to. So I think an internal notification is enough.

Clean up EP-Filter after delete project/endpoint

For endpoint_filter extension we should remove all the endpoint
to project associations when we delete the associated endpoint
or project. Otherwise list_endpoints_for_project and
list_projects_for_endpoint API will return 404 response if the
associated endpoint or project has been deleted. Also, there will
be a lot of dirty data remaining in the database.

Check url is in the 'self' link in list responses

Method RestfulTestCase.assertValidListLinks (test_v3.py) doesn't have
any information about the request, so the check of the 'self' url in
links collection is very general:

self.assertThat(links['self'], matchers.StartsWith('http://localhost'))

This fix adds an optional 'resource_url' parameter.

The ability for the assertValidListLinks methods to check the url will
also form the basis for testing of bug 1195037 ("Self" link in v3
collections omits any url filters).

To test this fix test cases in test_v3_identity.py were updated with the
optional 'resource_url' parameter.

Closes-Bug: #1348063.
