This provides an easy way to specify exclude patterns in config. It was
already possible via extraBackupOptions; this change creates a simpler,
similar to other backup services, way to specify them.
This commit also moves the indicator files out of the directory that's
being backed up, so that the directory remains static throughout the
backup operation.
Configures the `--cache-dir` parameter for the prune and check commands run after backing up. For `check`, also adds a `checkOpts` flag to enable using the cache, since that is disabled by default.
The backupPrepareCommand and backupCleanupCommand options offer a way to
run a script to prepare for backup and then cleanup it once finish.
