As of now, we do not have a single source of truth
when it comes to the terminology describing the various components
Watcher is made of. Hence, this is an attempt to formalize it into
a single document.

Today, the watcher Decision Engine is not relying on Ceilometer V2 API
to query the metrics necessary for the optimization algorithm.
This patchset update the documentation to use Ceilometer API with
watcher
Change-Id: I62cf0ea7b1766b00601f3dcbbbfe20b4a9567570
Querying compute.node.* with Ceilometer requires some additional
information in the cluster data model in order to build the
resource_id. This patchset add the attribute hostname and change
the query.

as of mitaka, the infra team won't have the resources available to
reasonably test py26, also the oslo team is dropping py26 support from
their libraries. sine we rely on oslo for a lot of our work, and depend
on infra for our CI, we should drop py26 support too.

This patchset is there to change the code structure.
The objective is to flatten the project file tree by merging
'api/' and 'framework/' into a single package. This also contains
some tidy ups in package naming (like using only singular nouns).
This should only affect file/folder names and their subsequent
import paths wherever they were used.

Since all oslo libs are now using the new versions installed using
pip, there is no need to keep the watcher/openstack/common/ folder.

The BaseStrategy interface was moved to another location but the
documentation wasn't updated accordingly, so here I updated this
import path.
As an extra, I also updated the description of the Solution which
also had an outdated import path.

This should make our 'dummy' strategy available for use.
I also removed all previously defined default goals, which means
that they will have to define it themselves from now on.
This can also be useful for future integration tests.

In several places in Watcher, there are statuses which corresponds
to a status in the respective life cycle. There were used past tense
everywhere, except "SUCCESS" which was written in present tense.
So I searched for all the occurences of this state, and replaced them
with their past tense form.

The objective is to make it more explicit that the 'service' project
is referring to the keystone service.
This changeset also updated the documentation to stay under the
limit of 80 per line.

Default channel used is named 'openstack'. But Watcher AMQP topics are
bound to 'watcher' channel. So, on RCPClient init, we have to set
the channel name to 'watcher' for the target.

The objective for this is to give the ability to extend the default
set of placement algorithms (i.e. strategies) currently available
in Watcher using Stevedore.
Now, you can add your new strategy as an entry point under the
'[watcher_strategies]' section.

In current implementation is not easy to use ceilometer.
Watcher must query metrics from the Telemetry v2 API to allow an easiest integration with OpenStack components (especially devstack).

This regression was caused when we upgrade the version of olso.
Unfortunately this issue wasn't picked up with the unit tests as
the cmds doesn't have unit tests yet.
Error message: "watcher-api fail with NoSuchOptError: no such option:debug"

- 'watcher-api' command
- 'watcher-db-manage' command (and sub-command)
- 'watcher-applier' command
