Fix https://github.com/paritytech/zombienet-sdk/issues/169

- Add logic to retrieve available args from node before spawning the
full network using the output of the command with --help

Add:
 - Logic to use db_snapshot in both native/k8s providers
 - Small fix on chain_spec_path (for both native/k8s)
 - New example `db_snapshot`

Add: Manual variant to `RegistrationStrategy`, allow to deploy the
collators _but_ not register the para.
Fix: `created_paths` in native provider
Fix: Use `rpc` port for ws connections (orchestrator)

This PR introduces the Kubernetes Provider for the SDK, with the use of
kube.rs for common operation and a custom file server using axum to
transfer files back and forth the nodes.

https://github.com/paritytech/zombienet-sdk/issues/35

This also includes the refacto of the native provider to reflect changes
to the provider structure with weak references and simplifying the use
of abstractions

Fix parachain spec filename (local) to use when we spawn collators.
Also, adding `Context` to spawner to improve error reporting.

Adding `tracing` and replace all the `println`. We should add more info
in a followup pr.
Thx!

just wanted to throw a quick implementation that exposes the
OnclineClient on the node.
This would make the sdk super useful to enable cross chain e2e tests in
ink!
