Subject: [PATCH 1/5] [#707] Filter snapshots by node's commit hash

Problem: The setup wizard can download snapshots from a provider
with metadata, but it doesn't filter these by Octez version.
This can cause issues in case a snapshot has been created
with an Octez version that is incompatible with the one being used.

Solution: Filter by node's commit hash.
