Current plugin imports is missing dmaap/clamp/postgres plugin and dashboard.url is incorrect (should be dashboard.url=https://dashboard/ccsdk-app/nb-api)

Update the following properties (and code) to have generic names

onap.import.cloudifyPlugin=http://www.getcloudify.org/spec/cloudify/3.4/types.yaml

onap.import.k8sPlugin=https://nexus.onap.org/service/local/repositories/raw/content/org.onap.dcaegen2.platform.plugins/R4/k8splugin/1.4.5/k8splugin_types.yaml

onap.import.policyPlugin=https://nexus.onap.org/service/local/repositories/raw/content/org.onap.dcaegen2.platform.plugins/R4/dcaepolicyplugin/2.3.0/dcaepolicyplugin_types.yaml

Including (https://git.onap.org/dcaegen2/platform/tree/mod/runtimeapi/runtime-web/src/main/java/org/onap/dcae/runtime/web/configuration/BlueprintCreatorConfig.java) 

        Path onapDublinImportFilePath = Paths.get("./data/imports/onapDublinImports.yaml").toAbsolutePath().normalize();

The filename could be changed such as onapImports.yaml
