Change unit string translation in volume limit templates

This fixes an issue where the lazy translated "GB" unit string is
not properly resolved in the volume limit templates. This error
does not happen in a devstack environment but has been found to
happen in chef and puppet deployed OpenStack production
environments.

Fixed add_bootstrap_class template filter

Made sure that the add_bootstrap_class filter correctly obtains the
widget type to prevent it applying the form-control css class onto
parts of forms that shouldn't have it.

Show floating IP associated with Load Balancer VIP

Previously the code always tried to show an instance when
a floating IP is associated. This commit chnages the code
to consider a port device_owner associated with a floating IP
so that appropriate information is displayed in the table.

Workaround for negative vals in total*Used in nova absolute_limits

Due to bug 1370867 there is a case where negative values are returned
in total*Used in absolute_limits. If it occurs, Horizon Overview page
cannot be displayed due to an error "cannot convert float infinity to
integer". This commit replaces negative values in total*Used with 0
for a workarond.
