Feature request: Update Tensorflow version to be compatible with Python 3.8+

[Tomcli]

In the KServe community, there are some users looking to use a newer Tensorflow and Python version to reduce the numbers of CVEs. Here is the related issue.
kserve/kserve#2364

[Tomcli]

The currently AIX360 has a hard dependency on Tensorflow 1.14.0 which only can work on Python 3.7 and below. Are there any plan to update Tensorflow to 2.2+ to support Python 3.8+ so the dependent projects can also update the python version?
