Description

Remove Stack v1 impl, StackCollector.collect_stack(). There still are tests/profiling and tests/profiling_v2 directories, and cleaning up those two will be done in a follow up PR.

One notable improvement from this PR is that StackCollector no longer inherits from periodic.PeriodicCollector, and PeriodicCollector is also deleted.

PeriodicCollector provided a mechanism to invoke a Python function periodically using a background native thread. For StackCollector it was needed to sample stack. stack_v2 creates its own background native thread and handles adaptive sampling its own. So we no longer need to have fields such as interval, max_time_usage_pct etc in StackCollector.
