🌟 feat(domain-config): Domain config for Tokens/LendingProtocols etc

[zerotucks]

Changes 👷‍♀️

• add Domain config
• create shared directory for common domain level items and types
• expose tokens, tokensByNetwork, lending protocols, networks and denomination symbols (for Subgraph/Token service)
• add addresses to tokensByNetwork from addresses package
• incorporate tokenSymbols into parts of OB config

Separate PR [Is out of date] -> (https://github.com/OasisDEX/oasis-borrow/pull/2973/files) have created a custom script to parse the config object and generate enums/interfaces for it.

Wanted to propose improved naming conventions for better readibility and maintainability of the code.

1. Enums usually use a singular form DenominationSymbol instead of DenominationSymbols, a lot of inconsistency here for example: LendingProtocol enum is singular but Networks enum is plurar

• It would be great to use a single convention and the singular form is preferable across the industry, e.g. check TS docs for reference: https://www.typescriptlang.org/docs/handbook/enums.html

2. Dictionaries usually use different conventions than arrays:

• tokens - I would expect that to return and array of tokens, but in reality it returns a dictionary mapping symbols to tokens
• I would like to propose to use clearer convention to name such dictionaries for example take a look at tokensByNetwork Which actually uses a pretty clear convention that on a first glance tell me that it contains a mapping of tokens with network as key
• So I would rename tokens to tokenByTokenSymbol

3. Also adding simple description comment for each dictionary object would be great but good name using convention should be enough
