cmd/snapshots: add gc.root to created snapshots

Browse Source 
This adds gc.root label to snapshots created with prepare and commit via
the CLI. WIthout this, created snapshots get immediately garbage
collected. There may be a better solution but this seems to be a solid
stop gap.

We may also need to add more functionality around snapshot labeling for
the CLI but current use cases are unclear.
