Policy service caching does not work within hz-dynamic-table

[Travis Tripp]

The policy service caching (where it ensures that if you look up the same policy more than once) does not seem to work under hz-dynamic-table.

Turn on ng-images which recently migrated to hz-dynamic-table and watch the network calls. You'll note a bunch of policy calls and if you look at the request body, you'll see the same rules going in multiple times.

    Memoize policy service

    There is a hole in the policy service caching layer
    that has something to do with ng-repeat. The angular
    http cache service doesn't seem to work within a single
    digest cycle or something... so I simplfied and
    improved performance by using memoize to
    prevent redundant checks which were happening in
    hz-dynamic-table.

    See bug for details on verifying this manually.
