Code Issues Proposed changes

Improve Glance profiling

Browse Source 
Put osprofiler middleware as a almost first middleware.
This allows us to:
1) Get more preciese duration. We are measuring duration of all middlewares.
2) authenticate middleware is requesting keystone, so if we init osprofiler
   before this middleware, we will get trace infomration from keystone as well.
