Move `Forbidden` exceptions to `RECOVERABLE` group

Previously the Forbidden exceptions raised by clients were classified
as UNAUTHORIZED. This classification is not entirely correct, as
the UNAUTHORIZED group of exceptions implies that the user should be
logged out and forced to log in again. This, however, is not the case
with Forbidden exceptions. Thus, it is more appropriate to place the
Forbidden exceptions into the RECOVERABLE group.

Integration tests - base class for all tests

The TestCase class will be the base for all tests, except the login
tests.
It contains two methods:
setUp - opens the login page, and performs the login to allow all test
start from the home page.

tearDown - returns the driver to the home page and logs out.

More clear message when detaching volume

When detaching a volume from instance, the warning message looks like:
You have selected "/dev/vdb on instance test". Please confirm your
selection. This action cannot be undone.
If we consider that not all user's will be familiar with linux they may
not understand that vda in this warning means boot disk.
So use "volume abc on instance test" like message instead of the origin
one.

not display loading image for rescued instances

If, any of the instances are rescued or shelved through CLI
those instances status are displayed as rescue or shelved offloaded
with a loading image.

Displaying the loading image for this two status are not correct.

Displaying the loading image is removed for
the rescue and shelved offloaded status.

Exception handling should not use exc.message

In looking at
https://review.openstack.org/#/c/77613/3/openstack_auth/backend.py , it
occurred to me that many other instances of e.message are likely lurking
throughout our code. And especially because Alex Gaynor decided to weigh
in, I think we have a somewhat authoritative view of how this should be
solved.

Refactor code around Console support

Add a console module to handle the different kinds on remote consoles
supported (vnc, rdp, spice ) and refactor the code
to use console.get_console.

In the future, a matrix based on HyperVisor could be added
in case that only one type of console is supported.
Ex: HyperV <=> RDP
