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.

Now that nodes correctly populate position field in coding shreds, and
first_coding_index in erasure meta, the old code to maintain backward
compatibility can be removed.
The commit is working towards changing erasure coding schema to 32:64.

This PR renames BlockstoreAdvancedOptions to LedgerColumnOptions, as we will
pass-down this struct to LedgerColumn to allow it to perform metric reporting.
As we start adding more options into BlockstoreOptions, it's better to allow
new_cf_descriptor to take the reference to BlockstoreOptions so that
we can avoid future function API changes on new_cf_descriptor.
Creating a new ledger implicitly means that no other process could have
previously held access to it. Additionally, creating a new ledger
implicitly requires writing, so it follows that Primary access is
required and we can drop access type as an argument.
#### Summary of Changes
This PR further enables group by operation on storage type in blockstore_rocksdb_cfs metrics.
Such group-by allows us to further compare the performance metrics between rocks-level and
rocks-fifo.
To make things extensible, this PR introduces BlockstoreAdvancedOptions and move shred_storage_type.
All fields in BlockstoreAdvancedOptions will support group-by operation in blockstore_rocksdb_cfs.
Dependency: #23580
* Rename excludes_from_compaction to should_exclude_from_compaction
* Make subfunction to create all cf descriptors
* Condense logic for when to disable compactions
This PR enables blockstore to periodically report RocksDB column family properties.
The reported properties are under blockstore_rocksdb_cfs, and the properties also
support group by operation on cf_name.
#### Summary of Changes
This PR adds two hidden arguments to the validator that allow users to use RocksDB's FIFO compaction for storing shreds.
--shred-storage <SHRED_STORAGE>
EXPERIMENTAL: Controls how RocksDB compacts shreds. *WARNING*: You will lose your ledger data
when you switch between options. Possible values are: 'level': stores shreds using RocksDB's default (level)
compaction. 'fifo': stores shreds under RocksDB's FIFO compaction. This option is more efficient on
disk-write-bytes of the ledger store. [default: level] [possible values: level, fifo]
--shred-storage-size <SHRED_STORAGE_SIZE_BYTES>
The shred storage size in bytes. The suggested value is 50% of your ledger storage size in bytes. [default:
268435456000]
#### Summary of Changes
To avoid mixing the use of different shred storage types, each shred storage type
will have its blockstore in a different directory.
This PR still keeps the RocksFifo setting hidden. The default ShredStorageType and
blockstore directory are still RocksLevel and `rocksdb`.
Will follow-up with PRs on making FIFO option public in ledger-tool and validator.
#### Test Plan
* Added a new test to verify the existence of `rocksdb-fifo` directory when FIFO compaction is used.
* Updated existing test to verify the current setting still store ledger under `rocksdb` directory.
* Manually ran ledger_cleanup_test with both level and fifo compaction and verified the resulting ledger.
* Ran a validator with this PR.
* Bump first-available block to first complete block
* Remove obsolete purges in tests (PrimaryIndex toggling no longer in use
* Check first-available block in Rpc check_slot_cleaned_up
