fix floating ip test that wasn't running

the associate_floating_ip negative test wasn't running because
the indent was wrong. This was uncovered when looking for unknown
names with pyflakes.

This makes the test run, and fixes the mispelling of floating to
make it actually pass.

Fix get Floating ip pools action name to match with its policy

Get Floating IP Pools is always responding 403 (Forbidden) cause its method
name, which is also being used as action name, doesn't match with the name in
policy.json file.
I opted for this approach cause it also fixes the different names between the
extension (which is named floating **ip** pools instead of floating pools) and
the backend.
Another good practice would be change the default_floating_pool option to
default_float_ip_pool, but that would require change the conf file and possibly
break some compatibility.

Fixes bug 1091668
