Summary:
Since we enabled parallelism in valgrind the logs now go to
t/valgrind_log-*, which doesn't match our pattern t/log-*, so those files don't
get printed in the sandcastle output. For this regex we really just want
to exclude t/run-* (these are shell scripts), so let's do that explicitly.
Test Plan:
ran the commands locally, will also look at sandcastle
results on this diff which will include these changes

Summary: The test `ObsoleteFiles` failed occasionally on slow device. This problem appears on Travis CI several times. The reason is that we did not wait until compaction jobs are finished in the test, while in slower device the background jobs take longer time to finish.

Summary:
My understanding is that the purpose of write stall triggers are to wait for auto-compaction to catch up. Without auto-compaction, we don't need to stall writes.
Also with this diff, flush/compaction conditions are recalculated on dynamic option change. Previously the conditions are recalculate only when write stall options are changed.
Test Plan: See the new test. Removed two tests that are no longer valid.

The call stack used to look like this during static initialization:

#4 0x000000000080305d in rocksdb::ThreadLocalPtr::InitSingletons() () at util/thread_local.cc:106
It involves outer/inner classes and the call stacks goes
outer->inner->outer->inner, which is too difficult to understand. We can avoid
a level of back-and-forth by skipping StaticMeta::InitSingletons(), which
doesn't initialize anything beyond what ThreadLocalPtr::Instance() already
initializes.
Now the call stack looks like this during static initialization:
#0 0x00000000008032c5 in rocksdb::ThreadLocalPtr::StaticMeta::StaticMeta() (this=0x7ffff683b300) at util/thread_local.cc:170

#2 0x000000000080305d in rocksdb::ThreadLocalPtr::InitSingletons() () at util/thread_local.cc:106
Test Plan:

#0 0x00000000005cee17 in rocksdb::port::Mutex::Mutex(bool) (this=0x7ffff69500b0, adaptive=false) at port/port_posix.cc:52

Summary: We rely on a basic evaluation logic: when using an expression `A || B`, the `B` part will only get evaluated when `A` fails. Therefore the task creation tool is guaranteed to run if previous build/test step failed. To indicate the correct return value to shell, the task creation tool will call `exit(1)` which will cause Sandcastle to mark it as a failure.
Test Plan:
- Land the changes.
- Trigger a RocksDB contrun - observe the results.
- Look at the results from the nightly runs and fix issues as necessary.
Current testing so far has been in isolation for various components.
