* Rename ExecutionMode to IsolationStrategy Execution mode is too generic name and can imply a lot of different aspects of execution. The notion of isolation better describes the meant aspect. And while I am at it, I also renamed mode -> strategy cause it seems a bit more appropriate, although that is way more subjective. * Fix compilation in wasm_executor tests. * Add a comment to IsolationStrategy * Update comments on IsolationStrategy * Update node/core/candidate-validation/src/lib.rs Co-authored-by: Bastian Köcher <bkchr@users.noreply.github.com> * Accomodate the point on interruption * Update parachain/src/wasm_executor/mod.rs Co-authored-by: Andronik Ordian <write@reusable.software> * Naming nits Co-authored-by: Bastian Köcher <bkchr@users.noreply.github.com> Co-authored-by: Andronik Ordian <write@reusable.software>
