Updates many dependencies to enable sawtooth validator to build and run on ARM. Fixes a memory leak that occurs when using the currently published image on ARM.

Some packages that were pulled in via apt install (ex. python3-pyformance, python3-grpcio, etc.) aren't published for ARM, so we need to install them via pip. To install them via pip, we need to lock versions for some of the packages to continue to use python3.6 and be compatible with Grid. Some packages need to be up-to-date and not version-locked. Installing packages via pip is done in steps, as some packages need to be finished installing before calling pip install ... for others.

This also removes the dependency declarations in setup.py and stdeb.cfg files, as these mostly refer to packages without compatible ARM versions published. They are also silent failures in the build process.

I suspect that using an updated version of lmdb resolved the memory leak.

Note: This only updates the bionic docker-compose files, since we are only supporting bionic.
