Title: [TSAN] Parameterize the hard-coded threshold of deflake in tsan test
A number of testcases in TSAN are designed to deal with intermittent problems
not exist in all executions of the tested program. A script called deflake.bash
runs the executable up to 10 times to deal with the intermittent nature of the tests.
The purpose of this patch is to parameterize the hard-coded threshold above via
When this cmake var is not set, the default value of 10 will be used.
