Allow decorators.attr to be conditional
There are cases where we want to conditionally apply an
attribute to a test function, for example, if SSH validation
is enabled then a test may run much slower than if it is not.
This adds a 'condition' kwarg to the attr() decorator which
behaves similarly to the 'condition' kwarg on the skip_because()
decorator.

+ The ``tempest.lib.decorators.attr`` decorator now supports a ``condition``
+ kwarg which can be used to conditionally apply the attr to the test
+ function if the condition evaluates to True.
