Add `agoric add <package-name>` command

[danishyasin33]

There is no easy way to install packages in the UI of an Agoric dapp. Currently user has to manually insert package name in packages.json file in the ui directory. This is inconvenient.

There should be a command similar to agoric add <package-name> that easily installs packages in the UI directory.

I believe Agoric uses workspaces to install packages in the dapp projects. So we will need to think about that while building this command.

• Tracked that the agoric cli commands are actually all written in packages/agoric-cli/src directory in the agoric-sdk
• In src there is a main.js file which consists of function for each command where the arguments and optional params are a parsed and then their corresponding functions are called.
• So I added a function function for add command.
• Since we not only need to install packages to the ui directory. So created a more generalized the command .
• So if we want to add react-toastify package to the ui directory's package.json, now we just need the command:
  • agoric add ui react-toastify
• For adding specific version run command:
  • agoric add ui react-toastify@1.2.4
• So generalized command is agoric add directory package@version
