we plan step-by-step keep increasing this default

This fixes an issue where the mumbai testnet node struggle to find
peers. Before this fix in general test peer numbers are typically around
20 in total between eth66, eth67 and eth68. For new peers some can
struggle to find even a single peer after days of operation.
These are the numbers after 12 hours or running on a node which
previously could not find any peers: eth66=13, eth67=76, eth68=91.
The root cause of this issue is the following:
- A significant number of mumbai peers around the boot node return
network ids which are different from those currently available in the
DHT
- The available nodes are all consequently busy and return 'too many
peers' for long periods
These issues case a significant number of discovery timeouts, some of
the queries will never receive a response.
This causes the discovery read loop to enter a channel deadlock - which
means that no responses are processed, nor timeouts fired. This causes
the discovery process in the node to stop. From then on it just
re-requests handshakes from a relatively small number of peers.
This check in fixes this situation with the following changes:
- Remove the deadlock by running the timer in a separate go-routine so
it can run independently of the main request processing.
- Allow the discovery process matcher to match on port if no id match
can be established on initial ping. This allows subsequent node
validation to proceed and if the node proves to be valid via the
remainder of the look-up and handshake process it us used as a valid
peer.
- Completely unsolicited responses, i.e. those which come from a
completely unknown ip:port combination continue to be ignored.
-
Reason:
- produce and seed snapshots earlier on chain tip. reduce depnedency on
"good peers with history" at p2p-network.
Some networks have no much archive peers, also ConsensusLayer clients
are not-good(not-incentivised) at serving history.
- avoiding having too much files:
more files(shards) - means "more metadata", "more lookups for
non-indexed queries", "more dictionaries", "more bittorrent
connections", ...
less files - means small files will be removed after merge (no peers for
this files).
ToDo:
[x] Recent 500K - merge up to 100K
[x] Older than 500K - merge up to 500K
[x] Start seeding 100k files
[x] Stop seeding 100k files after merge (right before delete)
In next PR:
[] Old version of Erigon must be able download recent hashes. To achieve
it - at first start erigon will download preverified hashes .toml from
s3 - if it's newer that what we have (build-in) - use it.
* fix "genesis hash does not match" when dev nodes connect
The "dev" nodes need to have the same --miner.etherbase in order to
generate the same genesis ExtraData by DeveloperGenesisBlock(). Override
DevnetEtherbase global var that's used if --miner.etherbase is not
passed. (for NonBlockProducer case)
* fix missing private key for the hardcoded DevnetEtherbase
Fixes panic if SigKey is not found. Bor non-producers will use a default
`DevnetEtherbase` while Dev nodes modify it. Save hardcoded
DevnetEtherbase/DevnetSignPrivateKey into accounts so that SigKey can
recover it.
* refactor devnet.node to contain Node config
This avoids interface{} type casts and fixes an error with
Heimdall.validatorSet == nil
* add connection retries to rpcCall and Subscribe of requestGenerator
Fixes "connection refused" errors due to node not ready to handle early
RPC requests.
* fix deadlock in Heimdall.NodeStarted
* fix GetBlockByNumber
Fixes "cannot unmarshal string into Go struct field body.transactions of
type jsonrpc.RPCTransaction"
* demote "no of blocks on childchain is less than confirmations
required" to Info (#8626)
* demote "mismatched pending subpool size" to Debug (#8615)
* revert wiggle testing code
new flag examples.

--https.addr="0.0.0.0"

also adds support for h2c to the http handler - http2 protocol without tls.
* call getEnode before NodeStarted to make sure it is ready for RPC
calls
* fix connection error detection on macOS
* use a non-default p2p port to avoid conflicts
* disable bor milestones on local heimdall
* generate node keys for static peers config
