* adds the onError option to operations
Adds the OnError option to operations.Options. OnError tells
corso whether to continue despite concurrent processing
errors, or to exit processing on any error. Also includes flag
support for setting the option. Only adds the options, does
not assert error handling behavior in corso.
* add --all and --data to backup create
Adds flags for backing up all exchange data, and
for isolating the data in the backup by data type.
Introduces validation and selector creation in
backup create. Switches the --user flag variable
type from a string to a []string.
* 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.
* hook up restore end-to-end
Now that GC and KW both provide restore operations for a
single message, we can hook up the end-to-end restore
process. Integration tests for this change will follow in the
next PR.
Introduces a NewRestore method to the Repository struct.
cli/restore/exchange now generates a restoreOperation
and kicks off a Run() when `corso restore exchange` is called.
The restore operation still only accepts the placeholder
Target string slice.
Adds the `corso restore` command to the cli (which only displays
a help menu). And adds the `corso restore exchange`
command (which also only displays a help menu) to the cli.
Further functionality (like the complete flags) will come later.
