* Testnet improvements
Increase timeout for reading
Add more logs
Offer endpoint can fail due to talkReq timeout, to avoid
test failure, retry it few times until success.
* Add concurrency to the content offers of neighborhoodGossip proc
And remove some whitespace
* Remove more whitespace and adjust for 80 char line limit
* Update fluffy grafana dashboard to include gossip offer results
* Sharing block header data around in a Portal history network (PoC)
- Rework PortalStream to have an instance per PortalProtocol (this
needs to be improved eventually). Each instance uses the same
UtpDiscv5Protocol instance.
- Add processContent on receival of accepted data
- Add dumb neighborhoodGossip: dumb in the sense that it only
offers one piece of content at a time.
- Add to / adjust populate_db to also allow for propagation of
the data and add debug rpc call: portal_history_propagate
- Add eth_rpc_client
- Add eth_getBlockbyHash (no txs or uncles) to eth API
- Add additional test to test_portal_testnet which loads 5 block
headers to 1 node, and offers this data to few nodes, which should
propagate it over the network further. Next query every node for
this data.
* Adjust paths on which Fluffy CI is triggered
* Add documentation on the local testnet
