1.0.0 and removed dcae.node.type and policy_get

* moved dcae.node.type and policy_get from lib
  to dcaepolicy plugin and dcae.node.type
* removed dependency on cloudify-plugins-common and requests packages
* removed discovery logic
  since the lib does not talk to policy-handler anymore
  - happens in the new dcaepolicy plugin now
* no more policy_apply_mode per policy node
  - it is up to component's blueprint to decide how to notify
    about policy change
