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)
Crds values of nodes with different shred versions are creeping into
gossip table resulting in runtime issues as the one addressed in:
https://github.com/solana-labs/solana/pull/17899
This commit works towards enforcing more checks and filtering based on
shred version by adding necessary mapping and api to gossip table.
Once populated, pubkey->shred-version mapping persists as long as there
are any values associated with the pubkey.
