Agent refactor

[slundqui]

This PR is the 3rd PR in a series of PRs for agent0 to support multiple pools.

The agent classes in agent0 is reworked in this PR. Here, the main changes include init_agent being a function of the chain as opposed to the pool. Additionally, many functions now take a pool argument to specify what pool the agent is making a trade on. There are helper functions for setting an active pool to avoid passing this argument in various functions, by calling it either in init_agent, or by calling agent.set_active(pool=...).

Additionally, the policy is now untied from the agent, such that an agent can hot-swap policies on the fly by calling the agent.set_active(policy=...) function.

• init_agent is now a function of a LocalChain or Chain object.
  • This function now takes an optional pool argument for setting an initial active pool.
• Many functions now require an active pool to be set, or an explicit pool to be passed in as an argument.
• PolicyAgent has been deprecated in favor of using LocalAccount.
• Moving many logging and bookkeeping configs from Hyperdrive and LocalHyperdrive to Chain and LocalChain respectively.
• No longer keeping track of wallet deltas, we get the wallet wrt a pool via get_wallet().
• Adding helper functions for get_long(), get_short(), get_lp(), and get_withdrawal_shares().
• LocalHyperdrive now has a flag for deploying on constructor, or attach to existing. This is necessary for the forking workflow.
• Added tests for unit and system fuzzing.
