Subject: Store and return data types for policies
X-Git-Tag: 2.2.0~7
X-Git-Url: https://gerrit.onap.org/r/gitweb?a=commitdiff_plain;h=refs%2Fchanges%2F64%2F100064%2F2;p=policy%2Fmodels.git

Store and return data types for policies

In this change, the data types of policy types are persisted to the
database. All policy types currently in the database are returned on all
policy type get requests. This will be made more intelligent in the next
review.

Issue-ID: POLICY-2315
Change-Id: I10065ab9b90e72114a453494fc706d8aabc50c0a
