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.

 ### Changed
+- `opentelemetry-bootstrap` not longer forcibly removes and re-installs libraries and their instrumentations.
+  This means running bootstrap will not auto-upgrade existing dependencies and as a result not cause dependency

 - Extends from [BaseInstrumentor](https://github.com/open-telemetry/opentelemetry-python-contrib/blob/main/opentelemetry-instrumentation/src/opentelemetry/instrumentation/instrumentor.py#L26)
 - Supports auto-instrumentation
   - Add an entry point (ex. https://github.com/open-telemetry/opentelemetry-python-contrib/blob/main/instrumentation/opentelemetry-instrumentation-requests/setup.cfg#L56)
-  - Add instrumentation package to `bootstrap.py` (https://github.com/open-telemetry/opentelemetry-python-contrib/blob/main/opentelemetry-instrumentation/src/opentelemetry/instrumentation/bootstrap.py#L37)
+  - Run `python scripts/setup.py` followed by `python scripts/generate_instrumentation_bootstrap.py` after adding a new instrumentation package.
 - Functionality that is common amongst other instrumentation and can be abstracted [here](https://github.com/open-telemetry/opentelemetry-python-contrib/tree/main/opentelemetry-instrumentation/src/opentelemetry/instrumentation)
 - Request/response [hooks](https://github.com/open-telemetry/opentelemetry-python-contrib/issues/408) for http instrumentations
 - `suppress_instrumentation` functionality
