Tenets:
1. Limit thread names to 15 characters
2. Prefix all Solana-controlled threads with "sol"
3. Use Camel case. It's more character dense than Snake or Kebab case
Each time a node generates gossip pull-requests, it sends out all the
requests to a single randomly selected peer:
https://github.com/solana-labs/solana/blob/fd7ad31ee/gossip/src/crds_gossip_pull.rs#L253-L266
This causes a burst of pull-requests at a single node at once. In order
to make gossip in-bound traffic less bursty, this commit fans out gossip
pull-requests to several randomly selected peers.
This should reduce spikes in inbound gossip traffic without changing the
average load which may help reduce number of times outbound data budget is
exhausted when responding to gossip pull-requests at the receiving node, and
reduce number of pull-requests dropped.
This commit adds CrdsEntry trait which allows generic lookups into crds
table. For example to get ContactInfo or LowestSlot associated with a
Pubkey, the lookup code would be respectively:
crds.get::<&ContactInfo>(pubkey)
crds.get::<&LowestSlot>(pubkey)
ClusterInfo is the gateway to CrdsGossip function calls, and it already
has node's pubkey and shred version (full ContactInfo and Keypair in
fact).
Duplicating these data in CrdsGossip adds redundancy and possibility for
bugs should they not be consistent with ClusterInfo.
