* store backup operation results in the backup manifest
Adds backup operation metadata like the outcome
statistics and selector definitions to the backup manifest
entry. These additional details will appear when users
call `corso backup list`.
* add e2e backup-restore integration test
Adds an e2e integration test that starts by backing up
data, and ends with restoring it. Also makes various
amendments to other code where necessary to
facilitate this exercise.
Update the backup operation to create RestorePoint and RestorePointDetails models in the repository
Add modelstore to the operation to allow backup/restore operations to update/query for corso models
Closes#268
* Change DataCollection to return channel directly
Precursor to restoring multiple items from kopia. Allows one to keep a
DataCollection open until all items are processed without blocking
consumers of the DataCollection (they can use a select-block if needed).
* Update tests for new DataCollection interface
* Handle context cancellation with DataCollection
Implements a mock exchange data collection that can be used to test without connecting to graph.
Currently returns a "fixed message" but we can extend this to return anything that implements io.Reader
e.g. a file that contains a serialized message.
