Disable Pandas usage logging for method calls inside @contextmanager functions

Currently, calls inside @contextmanager functions are treated as external for with statements.

For example, the below code records config.set_option calls inside ps.option_context(...)

with ps.option_context("compute.ops_on_diff_frames", True):
    pass 

We should disable usage logging for calls inside @contextmanager functions to improve accuracy of the usage data
