Show up to 1 decimal place for instance detail RAM

The current instance details page rounds the amount of RAM to the
nearest integer, which at GB and TB levels does not provide enough
fidelity to be useful, this patch allows the page to display up to one
decimal place if it is required, by changing the filter applied in the
template from mbformat to mb_float_format.

Fixed row deletion for deleted stack

Now heat returns stack with "stack_status == 'DELETE_COMPLETE'"
for deleted stack. Added corresponding check to ajax handler.

HTTPNotFound is not used anymore and deprecated. Removed except
block for it.

Added raise to generic "except Exception" block to prevent
internal errors inside horizon.
