Add dependencies from Dependency Manager to a deployment account

[chasefleming]

When installing dependencies using the Dependency Manager, the subsequent step involves adding the contracts you wish to deploy to the deployments section of your flow.json. This can be approached in a couple of ways:

• The process could be automatic, where it is assumed that you likely want to deploy the contracts to the emulator-account, unless specified otherwise through a flag.
• Alternatively, the default approach should not be to automatically add the contracts. Instead, there could be an option to use a flag to add them to deployments.

The command could look something like:

flow deps add testnet://35717efbbce11c74.Find --deployment-account=emulator-account

Note: you can also default to the emulator-account and then if an account is provided override it.

After thinking about it a bit, a better option might actually be an interactive approach. It could ask you on installing/adding if you want to add the contract it finds to deployments, detect the accounts available, and let you select which to add it to. There could also be an option for --skip-deployments if you are running this from a scenario where you'd want to avoid an interactive prompt.
