Use NodeWrapper to directly initialize node with labels

Browse Source 
Using NodeWrapper in the integration tests gives more flexibility when
creating nodes. For instance, tests can create nodes with labels or
with a specific sets of resources.

Also, NodeWrapper initialises a node with a capacity of 32 pods, which
can be overridden by the caller. This makes sure that a node is usable
as soon as it is created.
