Adds support for cooldown-time variable in scaling-policy
Cooldown time defines the minimum time that needs to happen between
each scaling action. If an alarm triggers before this has happened,
no action should be executed. When POL receives an alarm notification
it will check that the difference between the current time and the
last scaling action of the alarm's scaling policy is bigger than the
cooldown time.
During configuration of the scaling groups, POL will now store the
cooldown time of the scaling policy. Also, it adds a new last_scale
var to ScalingPolicy, which has as default the oldest time supported
by Python datetime.

Fixes StopIteration error in multi scaling group descriptor scenarios
The code was iterating over all vdus in a vnfd, instead of doing
so over the vdu refs inside the scaling-group. This lead to errors
when there was a vdu without the metric declared in the criteria.
It has been replaced to iterate over the vdus in the scaling group
descriptor, which is the correct behaviour.
This commit also fixes an error in the scale function, which was
still using the old db structure.

Removes filter param from osm-common function calls
The filter argument was replaced to q_filter. Instead of
renaming the keyword arg, now functions are called using
only positional args.

Adds handling of scaled life cycle operation
Configures alarms on vdus created after a scaling operation, which
correspond to the 'scaled' message, using the same handler used with
the 'instantiated' message, in which a check has been added to avoid
duplicate alarms.
It also fixes the vdu name used when creating the alarm through MON,
which is now the vdur name and not the vdu-id-ref used in the vnfd.
Finally, it adds a check for the scaling-type param in the scaling policy,
only executing the autoscaling logic if it is set to 'automatic'.
