This user story entails the initial exploration of supporting L2 resiliency in policy and playing with active/active mechanisms on a single site configuration.

A simplified initial version limited in scope is assumed:

console, pap, brmsgw, and the mariadb database are singleton components

pap registers with msb and is made available in the external api gateway.

brmsgw registers with msb and is made available in the external api gateway.

pdp-x (1+) registers with msb.

pdp-x discovers pap through msb service discovery, and retrieves config, etc ..policies through msb api gateway interface to pap.

pap pushing of policies to pdpx is dependent on knowing the pdp-x identities, a mechanism needs to be figured out.

pdp-d (1+) discovers pdpx through msb

pdp-d exercies guard functionality through msb(pdpx) .
