secret HMAC key.
2) It start tracing in case of proper trace headers and add
first wsgi trace point, with info about HTTP request

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.
