Working towards revising shred struct to embed versioning so that a new
variant can contain merkle tree hashes of the erasure batch. To ease out
migration the commit adds more type-safety by distinguishing data vs
code shreds at the type level.
Additionally having both data and coding headers in each shred is
redundant as only one is relevant for each shred. The revised shred type
in this commit will only have one type-specific header.

A VoteAccount may only wrap an account if the account owner is
solana_vote_program:id or equivalently this check returns true:
solana_vote_program::check_id(account.owner())
#### Problem
blockstore_db.rs becomes bigger.
#### Summary of Changes
Move trait ColumnMetrics and metric-macros to blockstore_metric.rs out from blockstore_db.rs.
#### Problem
blockstore_db.rs becomes bigger.
#### Summary of Changes
This PR creates blockstore_metric.rs and moves metric-related functions out from blockstore_db.rs.
Current slot stats are removed when the slot is full or every 30 seconds
if the slot is before root:
https://github.com/solana-labs/solana/blob/493a8e234/ledger/src/blockstore.rs#L2017-L2027
In order to track if the slot is ultimately marked as dead or rooted and
emit more metrics, this commit expands lifetime of SlotStats while
bounding total size of cache using an LRU eviction policy.
* added realtime cost checking logic to reject block that would exceed max limit:
- defines max limits at block_cost_limits.rs
- right after each bath's execution, accumulate its cost and check again
limit, return error if limit is exceeded
* update abi that changed due to adding additional TransactionError
* To avoid counting stats mltiple times, only accumulate execute-timing when a bank is completed
* gate it by a feature
* move cost const def into block_cost_limits.rs
* redefine the cost for signature and account access, removed signer part as it is not well defined for now
* check if per_program_timings of execute_timings before sending
* Create solana-poh crate
* Move BigTableUploadService to solana-ledger
* Add solana-rpc to workspace
* Move dependencies to solana-rpc
* Move remaining rpc modules to solana-rpc
* Single use statement solana-poh
* Single use statement solana-rpc
* Upgrade Rust to 1.52.0
update nightly_version to newly pushed docker image
fix clippy lint errors
1.52 comes with grcov 0.8.0, include this version to script
* upgrade to Rust 1.52.1
* disabling Serum from downstream projects until it is upgraded to Rust 1.52.1
