Writing Cohort Registry Store Connectors

The cohort registry store stores information about the repositories registered in the open metadata repository cohort.

Each server in the open metadata repository cohort has a cohort registry component to manage its registration with the cohort and maintain the contents of its local cohort registry store.

There is one local registration record describing the information sent to the other members of the cohort and a list of remote registration records received from the other members of the cohort.
