* Update aodh from branch 'master'
  - Integrate OSprofiler in Aodh
    
    * Add osprofiler wsgi middleware. This middleware is used for 2 things:
      1) It checks that person who wants to trace is trusted and knows
         secret HMAC key.
      2) It starts tracing in case of proper trace headers
         and adds first wsgi trace point, with info about HTTP request
    
    * Traces HTTP API calls
    * Traces DB (SQLAlchemy) calls

    HOW TO TEST?
    
    1. Install devstack with aodh as usual
    
    2. Install osprofiler
    
        pip install osprofiler
    
    3. Add these line to /etc/aodh/aodh.conf
    
       [profiler]
       enabled = true
       hmac_keys = SECRET_KEY
       connection_string = redis://localhost:6379 # example when using redis
    
    4. Pass HMAC_KEYS to client commands
        - aodh client with `--profile <HMAC_KEYS>`
        - openstack client with `--os-profiler <HMAC_KEYS>`
    
    Output will look like this:
    
    To display trace use the command:
    
      osprofiler trace show --html <TRACE_ID>
    
    5. Use osprofiler to get the trace
    
        osprofiler trace show \
            --connection-string redis://localhost:6379 \
            --out out.html \
            --html <TRACE_ID>
    
    6. Open that html file with browser and view the result
