[SYNPY-1298] flakey integration tests

[BryanFauble]

Problem:
Several unit tests are very flaky, or timeout after 6 hours.

Solution:
Introduced 2 new packages:

    pytest-rerunfailures~=12.0
    func-timeout~=4.3

1. The func-timeout is to time bound some calls
2. The rerunfailures allows us to add a decorator to tests and conditionally re-run them a number of time (It's rare for them to fail multiple times in a row)

Testing:

1. See latest pipeline: https://github.com/Sage-Bionetworks/synapsePythonClient/actions/runs/6681317916 - Note: The pipeline in the PR might fail because of newly introduced dependencies that might not be in the cached dependencies
