System tests

[slundqui]

This PR adds the first system test for elf-simulations.

Major changes:

• It's here! Adds a system test that runs from bots to postgres db on a local test chain.
• Adding custom bot for test fixtures that cycles through all trades with known amounts
• Moving acquire_data.py to be within chainsync package, and writing minimal entry point to call
  • Breaking change: data capture script renamed from acquire_data.py to run_chainsync.py
• Parameterizing acquire_data.py to allow for system tests
• Explicitly setting a precision and scale for the Numeric postgres type

Minor changes:

• Adding script for making vscode debugging pytest easier
• Moving helper function get_web3_and_contracts from agent0 to ethpy
• Adding coerce_float to all postgres getter functions
• Docstrings
• Formatting

Bug fixes:

• Fixed a bug that stores invTimeStretch as unscaled values
• Fixed a bug with postgres/python schema typing for maturityTime

TODO:

• Do more comparisons in system tests, e.g., how much base for closing longs, pool info, etc
• Break out system_test
• There are rounding issues with using in-memory sqlite, should use containerized postgres
  • system-test: Use postgres in tests instead of sqlite #836
