Use datatype in matchable translator

With the new changes to models/api, the full policy template will
be retrieved along with inherited policy types and datatypes.

Changed api caller to return tosca template instead of individual
policy type so all policy types and data types are available.

Changed stdmatchabletranslator to be able to flexibly go deep with
list/map of datatypes of attributes. NOTE: This should be re-factored
at a later date as its a bit messy.

The naming application was used to test this code, but it was determined
by the CCSDK team that they will not do filtering this release. Instead,
switched to combined results policy type to return the full policy type.

Issue-ID: POLICY-1740
