Adds `OSProfiler <https://docs.openstack.org/osprofiler/latest/>`_ support.
This cross-project profiling library provides the ability to trace various
OpenStack requests through all OpenStack services that support it.

security:
- |
`OSProfiler <https://docs.openstack.org/osprofiler/latest/>`_ support
requires passing of trace information between
various OpenStack services. This information is securely signed
by one of the HMAC keys, defined in the ``ironic.conf`` configuration file.
To allow cross-project tracing, the same key should be used for all
OpenStack services.
