A fifo rocksdb instance must be opened with max size parameter on the
fifo columns. To support this, we previously plumbed a constant up to
callers that provided a default if unbounded growth desired.
This change attempts to be more rusty by exposing an option for this
value, and converting the option to a constant at the lowest level
possible.
#### Summary of Changes
Removes the constant default for ShredStorageType::RocksFifo
as the shred storage size is either user-specified or derived
from --limit-ledger-size in #27459.
### Problem
When FIFO compaction is used while --rocksdb_fifo_shred_storage_size
is unspecified, the FIFO shred storage size is set to a const default based
on the default `--limit-ledger-size`.
### Summary of the Change
When --rocksdb_fifo_shred_storage_size is unspecified, it is now
derived from `--limit-ledger-size` by reserving 1500 bytes for each
shred.
#### Problem
The ledger-tool copy command currently assumes target_db uses the same
shred storage type as the source ledger.
#### Summary of Changes
This PR enables ledger-tool copy command to infer the target_db shred storage
type based on whether rocksdb or rocksdb_fifo exists under the target_db directory
(same way as how ledger-tool infers the shred storage type for the main db.)
If the ledger-tool is not able to infer the shred storage type of the target_db, then
the default level compaction will be used.
Add ledger-tool command print-file-metadata
#### Summary of Changes
This PR adds a ledger tool subcommand print-file-metadata.
```
USAGE:
solana-ledger-tool print-file-metadata [FLAGS] [OPTIONS] [SST_FILE_NAME]
Prints the metadata of the specified ledger-store file.
If no file name is unspecified, then it will print the metadata of all ledger files
```
RocksDB settings include an option to create_if_missing, which will
create missing columns or the entire rocksdb directory if starting from
scratch. However, create_if_missing functionality only works if the
session has Primary (read+write) access. Many ledger-tool commands only
need Secondary (read-only) access to the database, so these commands are
unable to open the Blockstore when a column must be added.
This change detects when Secondary access open fails due to missing
column(s) or files, opens the database temporarily with Primary access,
and then reattempts to open the database Secondary access.
Prior to this change, long running commands like `solana-ledger-tool
verify` would OOM due to AccountsDb cleanup not happening.

#### 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.

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
