Removed Default implementation for ShredType. ShredType should always be
explicitly specified, and not rely on default values.
Simplified single-arg Shred Error variants to use shorter syntax.
Renamed erasure blocks to shards, to be consistent with reed_solomon
crate and not to confuse with FEC blocks.
#### Problem
The RocksDB wrapper,`Rocks`, under blockstore_db is currently implemented
as a tuple with unnamed fields. Accessing its fields requires syntax like `self.0`
which limits readability.
#### Summary of Changes
This PR converts Rocks from tuple to struct so that it has more human-readable
fields.
Shred::new_empty_data_shred returns an invalid shred (i.e.
shred.sanitize() returns error). The method is only used in tests and
can be easily replaced with Shred::new_from_data. To keep the shred api
surface small, this commit removes this method.

#### Problem
Currently, even if SOLANA_METRICS_ROCKSDB_PERF_SAMPLES_IN_1K == 0, we are still doing
the sampling check for every RocksDB read.
```
thread_rng().gen_range(0, METRIC_SAMPLES_1K) > *ROCKSDB_PERF_CONTEXT_SAMPLES_IN_1K
```
#### Summary of Changes
This PR skips the sampling check when SOLANA_METRICS_ROCKSDB_PERF_SAMPLES_IN_1K
is set to 0.
#### Summary of Changes
This PR enables perf metrics reporting for RocksDB deletes.
Samples are reported under "blockstore_rocksdb_write_perf" with op=delete
The sampling rate is still controlled by env arg SOLANA_METRICS_ROCKSDB_PERF_SAMPLES_IN_1K
and its default to 10 (meaning we report 10 in 1000 perf samples).
#### Summary of Changes
This PR enables perf metrics reporting for RocksDB write-batches.
Samples are reported under "blockstore_rocksdb_write_perf" with op=write_batch
Its cf_name tag is set to "write_batch" as well as each write-batch could include multiple column families.
The sampling rate is still controlled by env arg SOLANA_METRICS_ROCKSDB_PERF_SAMPLES_IN_1K
and its default to 10 (meaning we report 10 in 1000 perf samples).
#### Summary of Changes
This PR implements the reporting of RocksDB write perf metrics to blockstore_rocksdb_write_perf
based on RocksDB's PerfContext. The default sample rate is 10 in 1000, and the env arg SOLANA_METRICS_ROCKSDB_PERF_SAMPLES_IN_1K can control the sample rate.
Previously, the metric reporting functions are implemented under LedgerColumnMetric.
However, there're operations like write batch which is issued by the function inside Rocks.
This PR moves reporting functions to its own dedicate mod so that both LedgerColumn and
Rocks can report column perf metrics.
#### Summary of Changes
This PR enables RocksDB read side performance metrics to report to blockstore_rocksdb_read_perf.
The sampling rate is controlled by an env arg `SOLANA_METRICS_ROCKSDB_PERF_SAMPLES_IN_1K`,
specifies the number of perf samples for every 1000 operations. The default value is set to 10, meaning
we will report 10 out of 1000 (or 1/100) reads.
The metrics are based on the RocksDB [PerfContext](https://github.com/facebook/rocksdb/blob/main/include/rocksdb/perf_context.h).
It includes many useful metrics including block read time, cache hit rate, and time spent on decompressing the block.
