#### Problem
Ledger-tool doesn't support shred-compaction-type other than the default rocksdb level compaction.
#### Summary of Changes
This PR enables ledger-tool to automatically detect the shred-compaction-type of the specified ledger.
#### Test Plan
New ledger-tool tests are added for both level and fifo compactions.
* slots_connected check used by ledger-tool should not require a full slot for snapshot slot
* Cleaner Result<Option<>> unwrap/default
* return false if no meta for starting slot
* Add clarifying comments
* working on local snapshot
* Parallelization for slot storage minimization
* Additional clean-up and fixes
* make --minimize an option of create-snapshot
* remove now unnecessary function
* Parallelize parts of minimized account set generation
* clippy fixes
* Add rent collection accounts and voting node_pubkeys
* Simplify programdata_accounts generation
* Loop over storages to get slot set
* Parallelize minimized slot set generation
* Parallelize adding owners and programdata_accounts
* Remove some now unncessary checks on the blockstore
* Add a warning for minimized snapshots across epoch boundary
* Simplify ledger-tool minimize
* Clarify names of bank's minimization helper functions
* Remove unnecesary funciton, fix line spacing
* Use DashSets instead of HashSets for minimized account and slot sets
* Filter storages uses all threads instead of thread_pool
* Add some additional comments on functions for minimization
* Moved more into bank and parallelized
* Update programs/bpf/Cargo.lock for dashmap in ledger
* Clippy fix
* ledger-tool: convert minimize_bank_for_snapshot Measure into measure!
* bank.rs: convert minimize_bank_for_snapshot Measure into measure!
* accounts_db.rs: convert minimize_accounts_db Measure into measure!
* accounts_db.rs: add comment about use of minimize_accounts_db
* ledger-tool: CLI argument clarification
* minimization functions: make infos unique
* bank.rs: Add test_get_rent_collection_accounts_between_slots
* bank.rs: Add test_minimization_add_vote_accounts
* bank.rs: Add test_minimization_add_stake_accounts
* bank.rs: Add test_minimization_add_owner_accounts
* bank.rs: Add test_minimization_add_programdata_accounts
* accounts_db.rs: Add test_minimize_accounts_db
* bank.rs: Add negative case and comments in test_get_rent_collection_accounts_between_slots
* bank.rs: Negative test in test_minimization_add_programdata_accounts
* use new static runtime and sdk ids
* bank comments to doc comments
* Only need to insert the maximum slot a key is found in
* rename remove_pubkeys to purge_pubkeys
* add comment on builtins::get_pubkeys
* prevent excessive logging of removed dead slots
* don't need to remove slot from shrink slot candidates
* blockstore.rs: get_accounts_used_in_range shouldn't return Result
* blockstore.rs: get_accounts_used_in_range: parallelize slot loop
* report filtering progress on time instead of count
* parallelize loop over snapshot storages
* WIP: move some bank minimization functionality into a new class
* WIP: move some accounts_db minimization functionality into SnapshotMinimizer
* WIP: Use new SnapshotMinimizer
* SnapshotMinimizer: fix use statements
* remove bank and accounts_db minimization code, where possible
* measure! doesn't take a closure
* fix use statement in blockstore
* log_dead_slots does not need pub(crate)
* get_unique_accounts_from_storages does not need pub(crate)
* different way to get stake accounts/nodes
* fix tests
* move rent collection account functionality to snapshot minimizer
* move accounts_db minimize behavior to snapshot minimizer
* clean up
* Use bank reference instead of Arc. Additional comments
* Add a comment to blockstore function
* Additional clarifying comments
* Moved all non-transaction account accumulation into the SnapshotMinimizer.
* transaction_account_set does not need to be mutable now
* Add comment about load_to_collect_rent_eagerly
* Update log_dead_slots comment
* remove duplicate measure/print of get_minimized_slot_set
Add in some CPU utilization metrics such as: number of vCPUs, clock frequency, average load across different time intervals, and number of total threads
Fix pre-check of blockstore slts during load_bank_forks. Now iterates from starting_slot to halt_slot via slot_meta.next_slots to confirm they are connected.
#### Problem
blockstore_db.rs has a mutual dependency between blockstore_metrics.rs.
#### Summary of Changes
This PR removes the mutual dependency by moving the option-related stuff
out from blockstore_db.rs to its new home --- blockstore_options.rs.
By doing this, we address the mutual dependency and also make the code cleaner.
* Add a check during ledger-tool create-snapshot startup to see if the snapshot slot is available
* check all slots from the start to snapshot_slot during load_bank_forks
* unwrap_or_default incremental snapshot slot before comparison
* Improve error messages on missing or not full slots
value_t_or_exit()! will error if the user doesn't specify a value at
runtime, use value_of() instead which will give either the default value
or whatever the user specified.
This PR renames BlockstoreAdvancedOptions to LedgerColumnOptions, as we will
pass-down this struct to LedgerColumn to allow it to perform metric reporting.
