provider: added k3d provider and lifecycle handlers
This change includes the following changes and features. 1. Added a new Interface type `E2EClusterProviderWithImageLoaderAndNodeLifecycle` which can be used to setup providers that extend the cluster lifecycle function around the nodes. 2. Enabled a `k3d` based provider with support for Node lifecycle management. 3. Existing Image loader related function and interfaces were augmented with `args ...string` to be able to provide additional arguments in case if the image load handlers need some of the additional config.
