Low level logic extraction analysis

[baktun14]

• We want to extract the low level logic that is shared in https://github.com/akash-network/akash-api like SDL parsing, etc.
• We want to get rid of the duplicated yaml test files in favor of the ones in akash-api

Plan to migrate akashjs:

1. Improve the existing documention for the current version of akashjs
2. Migrate all the low level logic to akash-api (chain-sdk)
   1. Create a new low level client class that will be the main configurable entry point of the library which will contain:
      • protobuf types
      • grpc/rest client sdk - auto generated with typed methods
      • SDL parsing/generation
      • Certificate generation
      • Any other left-over logic in akashjs
   2. Generate new akash-api(chain-sdk) npm package to contain all of the above
3. Create new version of akashjs -> client-js
   1. Create new core high level client class that will be the main configurable entry point of the sdk, which will re-expose chain-sdk
   2. Abstract all the cosmjs or other third party libraries
   3. Create sample code and documentation for browser and nodejs environment
   4. WIP Akashjs refactor to client-js #116
