Simplify bootstrap and generate code (#514)

- We now automatically generate bootstrap_gen.py file from the list of instrumentations present in the source tree.
- Bootstrap command now uses consumes this auto-generated list instead of keeping it's own local copy.
- We no longer uninstall packages before installing them as instrumentation package no longer specify libraries as dependencies so the edge cases are no longer there.
- We no longer try to install an incompatible version or force upgrade/downgrade an installed version. This used to leave systems in broken states which should happen no more.
