Subject: Merge from ECOMP's repository

Main Features
--------------

-  Async-Instantiation jobs mechanism major update; still WIP (package
   `org.onap.vid.job`)

-  New features in View/Edit: Activate fabric configuration; show
   related networks; soft delete

-  Support AAI service-tree traversal (`AAIServiceTree`)

-  In-memory cache for SDC models and certain A&AI queries
   (`CacheProviderWithLoadingCache`)

-  Upgrade TOSCA Parser and add parsing options; fix malformed TOSCA
   models

-  Resolve Cloud-Owner values for MSO

-  Pass X-ONAP headers to MSO

Infrastructure
--------------
-  Remove codehaus' jackson mapper; use soley fasterxml 2.9.7
-  Surefire invokes both TestNG and JUnit tests
-  Support Kotlin source files
-  AaiController2 which handles errors in a "Spring manner"
-  Inline generated-sources and remove jsonschema2pojo

Quality
--------
-  Cumulative bug fixes (A&AI API, UI timeouts, and many more)
-  Many Sonar issues cleaned-up
-  Some unused classes removed
-  Minor changes in vid-automation project, allowing some API
   verification to run

Hard Merges
------------
-  HTTP Clients (MSO, A&AI, WebConfig, OutgoingRequestHeadersTest)
-  Moved `package org.onap.vid.controllers` to `controller`, without
   plural -- just to keep semantic sync with ECOMP.

Reference commit in ECOMP: 3d1141625
