Selectors and Subscriptions
-------------------------------

The Acumos federation gateway supports polling other Acumos instances for
solutions using a subscription mechanism.  This subscription contains a
selector specifying which catalogs should be imported.

The form of the selector value can be:

    { "catalogId": "some-catalog-id" }

or:

    { "catalogId": [ "first-catalog-id", "second-catalog-id", ... ] }

where a catalog ID is the UUID of the catalog: something like
70c19e97-b37d-4738-b363-2d352b2d0f05.
