Summary:
Context:
OptimisticTransactionDB has not been covered by db_stress (including crash test) like TransactionDB.
1. Adding the following gflag options to to test OptimisticTransactionDB
- `use_optimistic_txn`: When true, open OptimisticTransactionDB to test
- `occ_validation_policy`: `OccValidationPolicy::kValidateParallel = 1` by default.
- `share_occ_lock_buckets`: Use shared occ locks
- `occ_lock_bucket_count`: 500 by default. Number of buckets to use for shared occ lock.
2. Opening OptimisticTransactionDB and NewTxn/Commit added per `use_optimistic_txn` flag in `db_stress_test_base.cc`
3. OptimisticTransactionDB blackbox/whitebox test added in crash_test.mk
Please note that the existing flag `use_txn` is being used here. When `use_txn == true` and `use_optimistic_txn == false`, we use `TransactionDB` (a.k.a. pessimistic transaction db). When both `use_txn` and `use_optimistic_txn` are true, we use `OptimisticTransactionDB`. If `use_txn == false` but `use_optimistic_txn == true` throw error with message _"You cannot set use_optimistic_txn true while use_txn is false. Please set use_txn true if you want to use OptimisticTransactionDB"_.

Test Plan:
**Crash Test**
Serial Validation
```
export CRASH_TEST_EXT_ARGS="--use_optimistic_txn=1 --use_txn=1 --use_put_entity_one_in=0 --occ_validation_policy=0"
make crash_test -j
```
Parallel Validation (no share bucket)
```
export CRASH_TEST_EXT_ARGS="--use_optimistic_txn=1 --use_txn=1 --use_put_entity_one_in=0 --occ_validation_policy=1 --share_occ_lock_buckets=0"
make crash_test -j
```
Parallel Validation (share bucket)
```
export CRASH_TEST_EXT_ARGS="--use_optimistic_txn=1 --use_txn=1 --use_put_entity_one_in=0 --occ_validation_policy=1 --share_occ_lock_buckets=1 --occ_lock_bucket_count=500"
make crash_test -j
```
**Stress Test**
```
./db_stress -use_optimistic_txn -threads=32
```

Summary:
This option allows a custom cleanup command line for a non-Posix file system to be used by db_crashtest.py to cleanup between runs.

Summary:
Expanded `all_params` to include all parameters crash test may set. Previously, `atomic_flush` was not included in `all_params` and thus was not visible to `finalize_and_sanitize()`. The consequence was manual crash test runs could provide unsafe combinations of parameters to `db_stress`. For example, running `db_crashtest.py` with `-atomic_flush=0` could cause `db_stress` to run with `-atomic_flush=0 -disable_wal=1`, which is known to produce inconsistencies across column families.
While expanding `all_params`, I found we cannot have an entry in it for both `db_stress` and `db_crashtest.py`. So I renamed `enable_tiered_storage` to `test_tiered_storage` for `db_crashtest.py`, which appears more conventional anyways.

Summary:
Having all of TMPD, TMPDIR and TEST_TMPDIR as configuration
parameters is confusing. This change simplifies a number of things by
standardizing on TEST_TMPDIR, while still recognizing the old names
also. In detail:
* crash_test.mk also needs to use TEST_TMPDIR for crash test, so put in
shared common.mk (an upgrade of python.mk)
* Always exporting TEST_TMPDIR eliminates the need to propagate TMPD or
export TEST_TMPDIR in selective places.
* Use --tmpdir option to gnu_parallel so that it doesn't need TMPDIR
environment variable
* Remove obsolete parloop and parallel_check Makefile targets
* Remove undefined, unused function ResetTmpDirForDirectIO()
