Add March 2021 VM based on Ubuntu 20.04 (#403)
* First draft of Ubuntu 20.04 Vagrantfile and scripts to install 2021-Mar
version of open source P4 development tools.

* Add more tracing output of what files have been installed at each step

* Don't do behavioral-model install_deps.sh before installing PI
This is an experiment to see if the end result will be able to run
tutorials basic exercise using Python3 only on an Ubuntu 20.04 system.
Just before this commit, `vagrant up` resulted in a system that failed
to run the basic exercise, because python3 failed to import
google.grpc (if I recall correctly -- it may have been a different
google.<something> Python3 module name).

* Add missing patch file

* Fix copy and paste mistake

* Add missing patch file

* Change how protobuf Python3 module files are installed

* Correct a few desktop icon file names, and add clean.sh script

* Enhance clean.sh script, and add README for manual steps in creating a VM

* Changes to try to always use Python3, never Python2, in tutorials

* Update README steps for preparing a VM

* More additions to README on steps to create a single file VM image

* Add empty-disk-block zeroing to clean.sh script

* Also install PTF

* Update versions of P4 dev tool source code to 2021-Apr-05
This includes a change to p4lang/PI that allows P4Runtime API clients
to send the shortest byte sequences necessary to encode integer
values, which I want for a PTF test that I have recently created.

* Update README for 2021-Apr-05 version of VM image

* Resolve Python 3 compatibility issues

Most of the Python 2 to 3 code translation changes
were automated with the 2to3 tool.
