Kim Altintop a675cb36d2 Expand scope of DurabilityProvider to include snapshotting (#3295 )

The `DurabilityProvider` trait was introduced to enable the
`HostController` to procure an alternative `Durability` impl from an
external source.

It is also useful to be able to instantiate a `SnapshotWorker`
externally, in order to subscribe to snapshot creation events without
access to the `RelationalDB` instance it is operating on.

At a later stage, we may also use it to control the snapshot frequency
externally.

This patch thus reframes the trait as `PersistenceProvider`, whose job
is to provide persistence-related services.

Also separates snapshot creation and compression of older snapshots, and
adds instrumentation to gather timing information for both.
