This commit
- adds a configuration in which no step holds, replication cursors, etc. are created
- removes the send.step_holds.disable_incremental setting
- creates a new config option `replication` for active-side jobs
- adds the replication.protection.{initial,incremental} settings, each
of which can have values
- `guarantee_resumability`
- `guarantee_incremental`
- `guarantee_nothing`
(refer to docs/configuration/replication.rst for semantics)
The `replication` config from an active side is sent to both endpoint.Sender and endpoint.Receiver
for each replication step. Sender and Receiver then act accordingly.
For `guarantee_incremental`, we add the new `tentative-replication-cursor` abstraction.
The necessity for that abstraction is outlined in https://github.com/zrepl/zrepl/issues/340.

// FIXME: properly abstract snapshotting:
|
|
// - split up things that trigger snapshotting from the mechanism
|
|
// - timer-based trigger (periodic)
|
|
// - call from control socket (manual)
|
|
// - mixed modes?
|
|
// - support a `zrepl snapshot JOBNAME` subcommand for config.SnapshottingManual
