This is a follow-up to: https://review.opendev.org/#/c/666897/
and makes sure titles and help information get rendered in
the configuration documentation and configuration samples.
The options for the placement_client group are already changed
and left untouched as a result. The changes to grafana_client
are already done in another patch and also untouched.

This patch implements uWSGI support for Watcher API service.
Because mod_wsgi is deprecated, using uwsgi to replace of mod_wsgi.
Most of Openstack projects have finished it.

Nova used to emit versioned and unversioned notiifcations
by default but that changed in https://review.opendev.org/603079/
so now nova emits only unversioned notifications by default.
Watcher listens for versioned notifications so we need to configure
nova to emit both versioned (for Watcher) and unversioned
(for Ceilometer) notifications explicitly.
This adds an override-defaults file so devstack will load up
the nova devstack variable to set the notification_format before
importing and stacking the nova lib script.
Note that this only fixes the non-grenade CI jobs since grenade
requires separate handling for overriding defaults which is proving
hard to do and will be addressed in a separate change.

In the process of handling instance_created.end,
there is a KeyError exception output log. This is because
invoking get_instance_by_uuid before creating the instance
in the data model.
During the review of https://review.opendev.org/#/c/663489/,
reviewers think that it's better to remove the KeyError exception.
This patche seperates the process of instance_created.end from
other Nova notifications and removes the call of get_instance_by_uuid.

Ceilometer removed cpu_util metric in [1].
Another metric compute.node.cpu.percent need to set
compute_monitors option to cpu.virt_driver in the
nova.conf, we should remind user about these.

Replaces the NoSuchMetric exception that was replaced. The exception
is replaced with MetricNotAvailable and test cases are added to prevent
regression.
The changes in the exceptions were introduced in:

In get_node_by_instance_uuid, an exception ComputeNodeNotFound
will be thrown if can't find a node through instance uuid.
But the exception information replaces the node name with
instance uuid, which is misleading, so we define a new exception.

Moves the query_retry method into the baseclass and makes the query
retry and timeout options part of the watcher_datasources config group.
This makes the query_retry behavior uniform across all datasources.
A new baseclass method named query_retry_reset is added so datasources
can define operations to perform when recovering from a query error.
Test cases are added to verify the behavior of query_retry.
The query_max_retries and query_timeout config parameters are
deprecated in the gnocchi_client group and will be removed in a future
release.

We should be starting from stable/stein on the "old" side
of grenade runs now. Rather than hard-code the branch, just
use the BASE_DEVSTACK_BRANCH variable.

In Python, when we use @property, the method will be
decorated by property.
When we call method self.strategy.datasource_backend()[1],
Actually it did two things:
1. call self.strategy.datasource_backend()
2. according to the method's return value[2], call self._datasource_backend()
[1]. https://github.com/openstack/watcher/blob/bd8636f3f/watcher/tests/decision_engine/strategy/strategies/test_base.py#L87
[2]. https://github.com/openstack/watcher/blob/bd8636f3f/watcher/decision_engine/strategy/strategies/base.py#L368
But in this part, we just want it to perform the first step.
So we have to use self.strategy.datasource_backend instead of
self.strategy.datasource_backend()
The reason why the unittest does not report an error is
because the returned value is a mock object, and the second step
is executed without error, for example:
python -m unittest watcher.tests.decision_engine.strategy.strategies.test_base
(Pdb) x=self.strategy.datasource_backend
(Pdb) type(x)
<class 'mock.mock.MagicMock'>
(Pdb) x
<MagicMock name='DataSourceManager().get_backend()' id='139740418102608'>
(Pdb) x()
<MagicMock name='DataSourceManager().get_backend()()' id='139740410824976'>
(Pdb) self.strategy.datasource_backend()
<MagicMock name='DataSourceManager().get_backend()()' id='139740410824976'>
To make the tests more robust, the underlying backend function
is mocked to be not callable.
