Config option 'backend' with parameter choices =['noop', 'statsd'],
that means oslo.config will ensure value is one of them, otherwise
a ValueError will be raised, so don't need handle and test config
option 'backend' with invalid value.

This change introduces a new base test class that mocks out
utils.execute() and similar functions and forces an exception if it
gets called. If utils.execute() is mocked by the test case then it
will work. What this does is prevent un-mocked access to
utils.execute() / processutils.execute() and similar subprocess
library functions.

Config option metrics/backend only accepts values "noop" or "statsd" [1],
however test_nonexisting_backend() checks for a different value.
oslo.config 4.0 will check overridden value type by default[2], so we
need to set enforce_type in CONF.set_override to allow unit tests to
pass.

This patch adds metrics to ironic-lib, so that it can be used by both
Ironic and IPA. It implements a generic MetricLogger including timers,
counters, and gauges with their respective decorators and context
managers. Two default MetricLogger are included: NoopMetricLogger and
StatsdMetricLogger.
