[Findit] Add test_label_name for Flake Model

This CL introduces test_label_name for the Flake data model,
test_label_name is the same as the normalized test name except that the
variable parts are replaced with '*' instead of being removed.

This CL also changes the issue tracker service to use the
test_label_name to file bugs. Another implication of this change is
that since the bug doesn't refer to any specific test instance anymore,
Flake Analyzer's bug description and bug comments are changed to
include the original test name, or otherwise, users would have no idea
which specific test instance Flake Analyzer is referring to.
