move the validation logic into executor (#2258) * move the validation logic into executor To allow more flexibility for the executor, we move the validate logic into the executor. The validate runs in the `create` step before workloads are executed. Instead of implementing the validation in the `exec`, to maintain backward competiability, we have to introduce an extra step. The exec is too late to fail if the spec is not validated.

# Migration Guide
Rename the rootless struct and correspondigs to UserNamespaceConfig and according.
2023-08-12 15:58:25 +02:00
This contains information for migrating library versions.
## V0.1.0 -> v0.2.0
### libcontainer
- The `Rootless` struct has been re-named as `UserNamespaceConfig` , `RootlessIDMapper` has been re-named to `UserNamespaceIDMapper` , and correspondingly the `RootlessError` has been re-named to `UserNamespaceError` . This is due to the fact that the structure was to be used for containers when a new user namespace is to be created, and that is not strictly only for rootless uses. Accordingly, the fields of various structs has been updated to reflect this change :

- Executor now contains 2 methods for implementation. We introduce a `validate` step in addition to execute. The `validate` should validate the input OCI spec. The step runs after all the namespaces are entered and rootfs is pivoted.
Rename the rootless struct and correspondigs to UserNamespaceConfig and according.

- Executor is now composible instead of an array of executor. To implement multiple executor, create a new executor that runs all the executor. The users are now in control of how multiple executor are run.
