DEV-3362: upgrade to sqlalchemy 2+ (#131)

- Upgrade sqlalchemy from 1.3+ to 2+, fixed a bunch deprecations both in test and in main code
- Reduced warnings in test from 688 to 6. The 6 is from external libraries
- Skipped 3 tests that do not execute as expected due to how the test were written (actual test was in an inner function)
- switch ddtrace.patch_all to ddtrace.auto as patch_all is deprecated and will be removed in future
