Separate CLI/clap related code, create a new `Config` struct to hold all
configuration/CLI args
Remove most code from `main.rs`
Add a little documentation
* Vote every number of ticks
* address review comments
* fix for failing leader rotation tests
* remove check for vote failure from replay tests
(as votes will be cached and transmitted when leader is available)
* Remove logging init from storage program: saw a crash in a test
indicating the logger being init'ed twice.
* Add entry_height mining proof to indicate which segment the result is
for
* Add an interface to get storage miner pubkeys for a given entry_height
* Add an interface to get the current storage mining entry_height
* Set the tvu socket to 0.0.0.0:0 in replicator to stop getting entries
after the desired ledger segment is downloaded.
* Use signature of PoH height to determine which block to download for
replicator.
* Reduce args in Tvu::new under to 8
Now pass in sockets through a the crate::tvu::Sockets struct
Move ClusterInfo.keypair to pub(crate) in order to remove redundant
signing keypair parameter
* remove commented code
Use 'network' for the networking stack. Examples:
* The network drops packets.
* The cluster rejects bad transactions.
* The Solana cluster runs on a gigabit network.
* Insert blobs into db_ledger in broadcast stage to support leader to validator transitions
* Add transmitting real slots to broadcast stage
* Handle real slots instead of default slots in window
* Switch to dummy repair on slots and modify erasure to support leader rotation
* Shorten length of holding locks
* Remove logger from replicator test
We followed the precedent set by the Rust book here, but now that
proposals are integrated, each proposal can simply include its own
terminology section.
