This patch does the following:
* Adds osprofiler wsgi middleware
This middleware is used for 2 things:
- It checks that person who wants to trace is trusted and knows
secret HMAC key.
- It starts tracing in case of proper trace headers
and adds first wsgi trace point, with info about HTTP request.
* Adds initialization of osprofiler at start of service
- Initialize and set an oslo.messaging based notifier instance
to osprofiler, which will be used to send notifications to Ceilometer.
* Traces HTTP/RPC/DB API calls and SQL requests
NOTE to test this patch:
1) Make the following changes in localrc to configure DevStack to enable
OSProfiler:
enable_plugin panko https://git.openstack.org/openstack/panko
enable_plugin ceilometer https://git.openstack.org/openstack/ceilometer
enable_plugin osprofiler https://git.openstack.org/openstack/osprofiler
# Enable the following services
CEILOMETER_NOTIFICATION_TOPICS=notifications,profiler
ENABLED_SERVICES+=,ceilometer-acompute,ceilometer-acentral
ENABLED_SERVICES+=,ceilometer-anotification,ceilometer-collector
ENABLED_SERVICES+=,ceilometer-alarm-evaluator,ceilometer-alarm-notifier
ENABLED_SERVICES+=,ceilometer-api
NOTE: the order of enabling plugins matters.
2) Run stack.sh. Once DevStack environment is setup, enable profiler options
in ironic.conf and restart ironic services:
[profiler]
enabled = true
hmac_keys = SECRET_KEY
trace_sqlalchemy = true
3) Use openstackclient and run baremetal command with
--os-profile SECRET_KEY
[--profile can be used, but it is deprecated.]
For example, the following will cause the <trace-id> to be printed
after node list:
$ openstack --os-profile SECRET_KEY baremetal node list
.....
.....
Trace ID: <trace-id>
Display trace with command:
osprofiler trace show --html <trace-id>
4) The trace results can be saved using this command:
$ osprofiler trace show --html <trace-id> --out trace.html

This change adds initial metrics for Ironic based on new support in
ironic-lib. Emits timing metrics for basic Ironic API calls.
Bumps ironic-lib to 2.0.0 in requirements to add metrics support, as
well as adding ironic_lib.metrics and ironic_lib.metrics_statds to
ironic-config-generator.conf to get them in the sample config, which
is also regenerated.

Partial-bug: #1526219
oslo_config provide a utility for generating sample config files,
which provide more detail about opts, like Minimum/Maximum value
and Allowed values.
So drop Ironic's "generate_sample.sh" which was copied from
oslo-incubator long time ago.
Add a new entry point "ironic" under oslo.config.opts namespace to
explore config options to oslo-config-generator.
After this patch, new config options of Ironic code should register
with ironic/conf/opts.py. New external libraries should
register with tools/config/ironic-config-generator.conf
There is a bug #1554657 with oslo-config about deprecated_group.
This bug have impact of some configs from keystonemiddleware
and oslo.messaging in ironic.conf.sample
So currently, deprecated option should always add the deprecated_group
even it didn't alter the group, otherwise the deprecated group value will
be 'DEFAULT'.
Update etc/ironic/ironic.conf.sample via running 'tox -egenconfig'.
