Truffle DB's Project abstraction lacks an easy read interface

[gnidan]

Issue

The @truffle/db Project abstraction allows loading compilations and migrations, but does not provide an easy means to query a particular project for contracts or contract instances, thus requiring someone who wants this data to construct a graphql query by hand.

Like, no one really wants to have to do this:

query {
  projects {
    contractInstances(
      contract: { name: "Example" }
      network: { name: "develop" }
    ) {
      contract { name } 
      address
      }
    }
}

Environment

• Operating System:
• Ethereum client:
• Truffle version (truffle version): v5.6.2
• node version (node --version):
• npm version (npm --version):
