kpdev fbc2b4d289 Integrate OSprofiler and Manila
*) Add osprofiler wsgi middleware

This middleware is used for 2 things:
1) It checks that person who want to trace is trusted and knows
secret HMAC key.
2) It start tracing in case of proper trace headers and add
first wsgi trace point, with info about HTTP request
*) Add initialization of osprofiler at start of serivce.

You should use python-manilaclient with this patch:

https://review.opendev.org/#/c/769731

Run any command with --profile SECRET_KEY

  $ manila --profile SECRET_KEY create NFS 1 --name <share> \
    --description <share_description> --share-network <network> \
    --share-type default
  # it will print <Trace ID>

Get pretty HTML with traces:

  $ osprofiler trace show --html <Trace ID> --connection-string \
   <connection_string> --out <output.html>
  e.g. --connection-string can be redis://localhost:6379

Note that osprofiler should be run from admin user name & tenant.

Implements: blueprint manila-os-profiler
