A description of the changes proposed in the pull request:
Adds Osmosis (with LP) support as a chain, plus some updates to Cosmos chain.
Cosmos amm.routes.ts models don't match up well with the rest due to inherent differences in their data. This has been handled by allowing certain endpoints to receive Cosmos-specific models switched by chain, eg. AddLiquidityRequest | CosmosAddLiquidityRequest.
Tests performed by the developer:
Jest tests added for all Osmosis functions. Very little patch use, instead a testnet wallet is instantiated and trades/liquidity actions are performed with it.
yarn test:cov is ~80% for Osmosis, improved for Cosmos.
Tips for QA testing:
THIS LINE MUST to be added to HBOT client native_tokens[]
"osmosis": "OSMO",
in hummingbot/core/utils/gateway_config_utils.py
Submitting separate PR for that file as well.
