Exclude more python tests in the FVTR
Exclude more python tests in the FVTR

In order for the FVTR to work, we need reliable tests.
Unfortunately, some of the python tests have been failing intermittently,
making it difficult to trust the entire python FVTR test.

In order to improve this situation, this patch excludes the following
python tests from the FVTR:
 - test_asyncgen
 - test_logging
 - test_poplib
 - test_threading
