Check license notes during build

Check license notes during build

I wanted to use oparent as parent pom but unfortunately jacoco plugin is
configured differently there. Currently oparent provides support for
jacoco (static code analysis), checkstyle (licenses + code style) and
swagger api documentation.

In ves-hv:
* jacoco is preconfigured for kotlin (but currently not very usable as
it's not ready for kotlin-generated code ie. displayed coverage is
well under the actual coverage; there is an ongoing effort in jacoco
and kotlin communities to fix that).
* checkstyle - this task adds support for checking licenses using
oparent:checkstyle artifact. Static code analysis is already done
using Detekt.
* swagger - ves-hv is not exposing REST API so there is no need for
this.

Closes ONAP-364
