HTTP retrievals only + more templates

[bajtos]

ETA: 2023-11-30

• Rework our job templates to use only (CID, SP) pairs supporting retrievals using the HTTP protocol.
• Enlarge our list of job templates to the top 1000 CIDs (or more). We need this for the next milestone, where we want to choose ~100 tasks per round. Selecting 100 random tasks from 200 templates wouldn’t work that well.
• Rework the SPARK module and hard-code retrievals to use the HTTP protocol.

• HTTP Gateway transport has code 2336 (0x0920)

We can get top 1000 CIDs from Saturn here: https://orchestrator.strn.pl/top-cids?limit=1000

In Saturn's TOP 1000 CIDs, only web3.storage advertises HTTP protocol to IPNI. If we disabled protocols other than HTTP, then SPARK would become a checker for web3.storage only, which does not make sense to me. Let's keep testing all three protocols (bitswap, graph sync, http) for now.
