Merged origin / master to StabilizeTests branch and then ran full FASTER pipeline as well as CI. Also ran local tests on Debug \ Release - Any CPU etc and all passed.

…re caused by log allocation sizes being too big. I reduced several tests to try to stabilize the tests in all configs.
…CPU config. Getting out of memory errors so reduced the size of the KV Log.

…). Remove Console.WriteLine in tests and replace with Debug.WriteLine in LocalMemoryDevice. Fix RecoverTests Segment and Page SizeBits to match reduced LMD capacity argument
…ure device and logs are cleaned up properly when the test is done.

This reverts commit 7b247e3.

* Updating KV DiskWriteScanBasicTest to be multiple device type tests

* Seeing CommitAsyncPrevTask test duplicated. One was multiple device type test and one was hard code to one device. Remove one hard coded to one device type.

* Exiting out of test CommitAsyncPrevTask and CommitNoSpinWait due to unstable test runs using Sleeps.

* Rolling back the test changes in CommitAsyncPrevTask, CommitNoSpinWait and put back the dupe of CommitAsyncPrevTask as now seeing fails in CI

* Updated several KV Basic tests to be multi Device Type tests

* Commented out a few FasterLog tests that have sleeps in them so can work to remove sleeps to stabilize test runs

* Rolling back Multi Device tests for KV Basic tests due to instability when running CIs ... will investigate more

* Rolling back tests in Faster Log that were commented out as causing funky results in CIs

* Had bug in KV  Log Basic test code that had multiple device test code still in there.

* Commented out CommitAsyncPrevTask in attempt to stabilize CI test queue

* Preliminary check in to get a bunch of KV Basic tests move to testing all device types

* Setting deleteOnClose when creating device to see if that is causing memory corruption

* Trying to get KV basic tests to not pop exception for memory corruption on CI machine

* Made a couple KV basic tests to test on all four device types

* Updated more KV basic tests to run all four device types as part of the test

* Categorized tests as "Smokes" to give good representation of tests that can be used as CI smokes

* Made MemoryLogCompactionTest1 to do four device type tests as need at least one compaction test to test all four device types. Not part of smokes

* Investigated why couple tests failed on LocalMemory device Type and either filed bugs or fixed code. Also, commented out two duplicate tests.

* Removed three duplicate tests ... guessing a merge issue at some point.

* Updated CommitAsyncPrevTask to not use Sleep since there is wait on the current task

* Removed a sleep in ManagedLocalStoreBasicTest as wasn't needed since the commit had true for parametre (wait until commit finishes before moving on)

* Updated WaitForCommitBasicTest to be multi threaded instead of using Sleep().

* Updated TearDown as it was missing the DeleteDirectory() call.

* Various test cleanup
- Centralize "RunAzureTests" checking
- Change GenericLogCompactionTests to illustrate using TestContext.CurrentContext.Test.Arguments
- Resolve bugs
  - #142980 - Blob not exist exception in Dispose so use Try \ Catch to make sure tests run without issues
  - #143432 - DeltaLogTest on LocalMemory is only returning 50 items when should be returning 200
  - #143433 - RecoveryTestFullCheckpoint - LocalMemory only - only reading 1 item when other devices reading all 16384 items

* Throw if incompatible sector sizes when writing files. Add Recovery tests by allocator type, and include failure tests of the sector-size throw

* Clean up AzureStorageDevice to use GetAwaiter().OnComplete instead of unawaited ContinueWith(); fixes the following bugs:
- Completes the fix for #143131 (fht.Log.Scan failing to get proper value on EmulatedAzure only) TestUtils.CreateTestDevice now uses Path.GetFileName(fileName) rather than a constant string
- Fixes #136259 (ReadFlags.SkipReadCache part of ReadAtAddress - SingleReader needs to be fixed to match SingleWriter)

* Fix typo in 25-fasterkv-recovery.md. (#555)

`(seq % 1L << 20)` = 0 for any `seq`, should be either `seq % (1L << 20)` or `seq % fht.IndexSize`.

* [C#] Stabilize tests (#551)

* Seeing Out of Memory failures on Release \ Any CPU test runs. These are caused by log allocation sizes being too big. I reduced several tests to try to stabilize the tests in all configs.

* Stabilized a few tests that were sporadically failing on Release Any CPU config. Getting out of memory errors so reduced the size of the KV Log.

* RecoveryTestByAllocatorType was failing on Debug x64 due to the log size was not valid. So putting size back to what it was

* Change Assert.IsTrue -> Assert.AreEqual (and other more-precise calls). Remove Console.WriteLine in tests and replace with Debug.WriteLine in LocalMemoryDevice. Fix RecoverTests Segment and Page SizeBits to match reduced LMD capacity argument

* Restore RecoveryTests Segment and Page SizeBits per Darren's push

* Updated a couple Device Faster Log Tests to use "using var" to make sure device and logs are cleaned up properly when the test is done.
