Migrate `policies` from being a `Set<Policy>` to a `policyMap`, that's a
`Map<String, Policy>`. The key defines the permission whereas the value
is the actual policy object. This makes it easier to use this data in
code, to query as a MongoDB nested document, and as a Postgres `jsonb`
column. Win-win!
The migration runs for all collections in parallel, with following stats
taken on 1-Jul-2024.
1. Release data, only non-deleted documents, all collections, parallel,
2m 42s.
2. Prod replica data, only non-deleted documents, all collections,
parallel, (15m).
3. Release data, only non-deleted documents, all collections, serial,
~9m.
This PR is only part of the solution. We have backwards compatible
`getPolicies()` and `setPolicies()` methods so the diff isn't too big,
but a follow-up PR will remove those two, and migration all usages to
use the map instead.
This PR only (almost) strictly includes changes that were necessary for
the build and tests to pass.
