Reduce environment logging

The log message for configuring the environment as eventlet was
at the info level. Operators don't find this detail interesting
so this should be logged at debug level.

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.

Closes-Bug: #1302106
