reporting views. The present commit brings the required changes in
community to have sample data in dashboard views.

Some web actions/controllers/viewsl have been adapted to properly instantiate the
newly refactored control panel and update it accordingly. We needed to adapt the
starting mechanism of actions and controllers to ensure that the control panel
instantiation did not delay the loading of any widget.

A pie chart widget aims to instantiate a graph view in mode
'pie', with a measure and a single groupby specified via some
attributes. It turns out that if a pie chart is instantiated
in a context in which the keys 'graph_mode', 'graph_measure',
and 'graph_groupbys' are present, that keys prevail over the
pie chart specification. This can produce a line chart for
instance. This fix corrects that situation.

A test has been added in a corresponding commit in enterprise
(historically, the pie chart widgets are tested in dashboard
views).

The Pie Chart title is not translatable, since a string defined in a
`t-att-` cannot be translated.

We use the attribute `title` instead.

This branch introduces a large-scale reorganization of the
component tree generated by the web client.  The short version is
that now, the control panel is a child of the view controller and
no longer a sibling. Graphically (and simplified), we go from
this:

                  webClient
                 /    |    \
               ...   ...  actionManager
                           /         \
                   controlPanel   viewController
                                    /       \

to this:

           	  webClient
                 /    |    \
               ...   ...  actionManager
                               |
                          viewController
                            /   |   \
          ControlPanelController
              /           \

The motivation is that this work moves the code where it should be.
Before this commit, it was kind of weird to have code in the
controllers to render buttons outside of their root node (in
renderButtons).  Also, the action manager had to take care of
coordinating search view states between view transitions.

So, this work simplifies the code.  It also makes it easier to
extend. We see day after day that Odoo needs to take care of more
complex UI needs, and in many cases, these needs were quite
difficult to implement (we prefer spaghettis in our plates, not in
our code).  The changes in this branch should open the way to
implement these features.

For example,
- it will now be easy to add the possibility of views (for example,
  the search view or a new ControlPanel view) to add custom buttons
  (of type action or object) in the control panel.
- Another need will be to serialize/ restore the state of the
  search view across action boundaries (needed by the dashboard).
- Another example is the possibility for views to customize easily
  the presence/absence of sub menus (filters/groupbys/favorites/
  time range/...)
- Another need is an easier way for views/client action to customize
  their control panel.

This commit also contains a large rewrite of the search view (so it
is more inline with our architecture and easier to maintain).
