Fix/load bp jsons 1053

[Torresmorah]

Limit how many bpjsons are requested

What does this PR do?

• Resolve Mainnet is not loading BP JSONs correctly #1053
• Limit the number of BP JSONS requested to 100
• Add a timeout when an endpoint of the array is requested
• Don't use statService when stateHistoryPluginEndpoint is not provided, in that case it would be called after loading the data from the producers.

Steps to test

1. Run the project locally
2. Check that the producers that aren't in the top 100 don't have bp.json
   and those in the top have the object
