move backfill sync jobs from highest priority to lowest (#3215)

Browse Source 
## Issue Addressed
#3212 

## Proposed Changes
Move chain segments coming from back-fill syncing from highest priority to lowest

## Additional Info
If this does not solve the issue, next steps would be lowering the batch size for back-fill sync, and as last resort throttling the processing of these chain segments
