Fix animation on pie charts

Animation on pie charts in Project > Overview and Admin > Hypervisros
does not start at 0 degree which, depending on the percentage used
for a resource, could cause the pie chart animate counter-clockwise.
This patch fixes the issue by setting the start angle to 0 degree.

The patch also fixes the issue with the last pie chart where it does
not animate.

Adds support for Nova RDP console

Hyper-V employs RDP to access virtual machine consoles, unlike most
other hypervisors which support VNC.

In order to support this scenario, the get_rdp_console API has been
added to Nova. This commit adds the corresponding UI feature,
implemented in a way consistent with existing VNC and SPICE console
support.

Host aggregates panel.

On this panel, aggregates could be added, deleted and edited.
This patch takes the aggregates panel out of System Info and
puts it back in the main admin panel list, as now, aggregates
are not static information. The host can be associated to a
host aggregate on this panel as well.
