Activity Spec - change in package and group names

1 Package structure will now be org.onap.sdc.activityspec instead of
org.openecomp.activityspec
2 Same applies for group names
3 This is done to fix issue with pushing docker images to nexus
repository
4 In ONAP in order for you to push to nexus you need to match the package
 and artifact name to the repository
