Fix Jenkins translation jobs

The jobs keystone-propose-translation-update and
keystone-upstream-translation-update do not update from
transifex since our po files contain duplicate entries where obsolete
entries duplicate normal entries.

Remove all obsolete entries to fix the jobs.

NOTE: This is NOT a clean backport of the patch from master, but rather
this patch was generated similarly to the patch to master using

Sanitizes authentication methods received in requests.

When a user authenticates against Identity V3 API, he can specify
multiple authentication methods. This patch removes duplicates, which
could have been used to achieve DoS attacks.

For ldap, API wrongly reports user is in group

When the ldap identity backend is configured,
HEAD v3/groups/​{group_id}​/users/​{user_id}
always returns 200, even if the user is not actually in the group.
This is because the sql and kvs backend will raise NotFound
exception if the user is not in the group, but the ldap backend
just return result.

Remove legacy_endpoint_id and enabled from service catalog

Those two fields are for internal use, and should not be in the token.

The token size was expanding past the threshold where it could
be passed between a wsgi process and Apache HTTPD, even for
a basic, devstack sized catalog.  This reduces the size.

Fix invalid LDAP filter for user ID with comma

The Keystone server would respond with a 500 error when configured
to use the LDAP identity backend and a request is made to get a
token for a user that has an ID with a comma. The response is like:

 Authorization Failed: An unexpected error prevented the server from
 fulfilling your request. {'desc': 'Bad search filter'} (HTTP 500)

This is because the user DN wasn't properly escaped in the filter
for the query to get the groups that the user is a member of.
