This commit performs a refactor of the
swift::storage::config to use fragments.
Updates server templates
- makes workers,user, and mount_checks configurable
- adds a default for concurrency
- makes the pipeline configurable
- remove vm_test_mode flag
Updates swift::storage::server to use fragments for
the config file.
This has been refactored to allow the end user a
greater level of flexibility over how they can
configure custom plugins for swift.
Also adds additional class params: pipeline,
mount_check, user, workers, concurrency.
Update the unit tests for swift::storage:server
