Only expose ConnectionPool from RedisService to avoid using Database or ConnectionMultiplexer directly.

- Each tool can have a number of deployments which are rolled out over time. Clients can specify a "phase" value indicating where in the queue they want to take updates (ie. whether they want to be early- or late-adopters), and deployments can be paused and cancelled.
- Tool channels are configured through the global configuration file. Tools can be marked "public", meaning that they do not require authentication against Horde for access. This can be useful for auto-update scenarios.
- The most recent 5 deployments are kept in the tool at any time.
The collection and controller implementation here is an experiment in reducing the amount of boilerplate currently adopted as a pattern in Horde. Notably:
- Model and collection classes are concrete rather than interfaces (since we don't generally mock them anyway).
- The same model class with annotations is used for response objects (paving the way to supporting patching and filtering using the same public model as the internal model).
- The VersionedCollection class is used to handle automatic migration of documents across schema versions, and cache document values with Redis.
- MongoDB property names are explicit and short, rather than just taking variable names.

- Versioned collections support individual versioning of each document, through a discriminator that distinguishes between different possible implementations of the document.
- All documents are derived from a common base class which includes an id field, and last update timestamp.
- Atomic operations on documents are supported by querying the last update timestamp before applying updates.
- Documents are cached in Redis whenever read or updated, allowing for performant access without directly accessing the database.
