PowerShell seems to have a hard time when a flood of async tasks is
scheduled at the same time.
I speculated that WaitForMultipleObjects() in Windows can only take up
to 64 process handles and if you want to handle more than you should write
some additional code which can be sub-optimal. I.e to implement Wait-Job -Any.
I decided to test that suggestion and introduced a $Concurrency parameter with a default value of 62.
So in the new version the script fires up up to $Concurrency value
and wait for anything to complete before starting any more processes.
This improved matters greatly. Individual tests against ramdrive now
run in 8 minutes and all of the 200+ db_tests run in 9 minutes with concurrency
values of 8-16. About 48 is required to load a CPU on my box running against HD
but that does not improve running times much.
Other changes include respect -EnableJE for the individual test exes.
Enforce exclusions for the individual tests.

Summary:
MyRocks testing found an issue that while iterating over keys
that are outside the prefix, sometimes wrong results were seen for keys
outside the prefix. We now tighten the range of keys seen with a new
read option called prefix_seen_at_start. This remembers the starting
prefix and then compares it on a Next for equality of prefix. If they
are from a different prefix, it sets valid to false.

Summary:
This diff is a first step towards an iterator based interface for the
SearchRadial method which replaces a vector of GeoObjects with an
iterator for GeoObjects. This diff works by just wrapping the iterator
for the encapsulated vector of GeoObjects. A future diff could extend
this approach by defining an interator in terms of the underlying
iteration in SearchRadial which would then remove the need to have
an in-memory representation for all the matching GeoObjects.
Fixes T8421387

The existing tests have been modified to work with the new
interface.

Summary:
The goal of this diff is to create a simple stress test with focus on catching:
* bugs in compaction/flush processes, especially the ones that cause assertion errors
* bugs in the code that deletes obsolete files
There are two parts of the test:
* write_stress, a binary that writes to the database
* write_stress_runner.py, a script that invokes and kills write_stress
Here are some interesting parts of write_stress:
* Runs with very high concurrency of compactions and flushes (32 threads total) and tries to create a huge amount of small files
* The keys written to the database are not uniformly distributed -- there is a 3-character prefix that mutates occasionally (in prefix mutator thread), in such a way that the first character mutates slower than second, which mutates slower than third character. That way, the compaction stress tests some interesting compaction features like trivial moves and bottommost level calculation
* There is a thread that creates an iterator, holds it for couple of seconds and then iterates over all keys. This is supposed to test RocksDB's abilities to keep the files alive when there are references to them.
* Some writes trigger WAL sync. This is stress testing our WAL sync code.
* At the end of the run, we make sure that we didn't leak any of the sst files
write_stress_runner.py changes the mode in which we run write_stress and also kills and restarts it. There are some interesting characteristics:
* At the beginning we divide the full test runtime into smaller parts -- shorter runtimes (couple of seconds) and longer runtimes (100, 1000) seconds
* The first time we run write_stress, we destroy the old DB. Every next time during the test, we use the same DB.
* We can run in kill mode or clean-restart mode. Kill mode kills the write_stress violently.
* We can run in mode where delete_obsolete_files_with_fullscan is true or false
* We can run with low_open_files mode turned on or off. When it's turned on, we configure table cache to only hold a couple of files -- that way we need to reopen files every time we access them.
Another goal was to create a stress test without a lot of parameters. So tools/write_stress_runner.py should only take one parameter -- runtime_sec and it should figure out everything else on its own.
In a separate diff, I'll add this new test to our nightly legocastle runs.

On Windows two tests fail that use MockTable:
flush_job_test and compaction_job_test with the following message:
compaction_job_test_je.exe : Assertion failed: result.size() == 4,
file c:\dev\rocksdb\rocksdb\table\mock_table.cc, line 110
Investigation reveals that this failure occurs when a 4 byte
ID written to a beginning of the physically open file (main
contents remains in a in-memory map) can not be read back.
The reason for the failure is that the ID is written directly
to a WritableFile bypassing WritableFileWriter. The side effect of that
is that pending_sync_ never becomes true so the file is never flushed,
however, the direct cause of the failure is that the filesize_ member
of the WritableFileWriter remains zero. At Close() the file is truncated
to that size and the file becomes empty so the ID can not be read back.
Summary: It looks like WritableFileWriter::Append() was returning OK() even when there is an error
