Create get Pdp Groups flow
Create a camel flow to get the list of Pdp Groups info from Policy. Create a scheduler to trigger the camel flow regularly and store the Pdp Groups info into DB. Issue-ID: CLAMP-644, CLAMP-649 Change-Id: I6427202cc0186cd85428d5d25b28a8622e4d7ca4 Signed-off-by: xuegao <xg353y@intl.att.com>
