services - high-level build functions to create layers

[devmatteini]

Instead of doing these operations

const MyMongoClient = MongoClientService.Tag("MyMongoClient")
const MyDbLive = DbService.layer(MyDb, MyMongoClient, "mydb")
const MyMongoClientLive = MongoClientService.layer(MyMongoClient, "mongodb://localhost:27017")

we could have some high-level build functions

const MyDbLive = SomeService.DONT_CARE_ABOUT_EXPLICIT_MONGO_CLIENT_SERVICE(MyDb, "mydb", "mongodb://localhost:27017")

Iteration 1

const MyDbLive = SomeService.layer(
  MyDb,
  {
    database: { name: "mydb", anyOption: true },
    client: { url: "mongodb://localhost:27017", anyOption: 1000 }
  }
)

const MyDbLiveEffectful = SomeService.layerEffect(
  MyDb,
  Effect.gen(function*() {
    const databaseName = yield* Config.string("MONGO_DATABASE_NAME")
    const clientUrl = yield* Config.string("MONGO_CONNECTION_STRING")
    return {
      database: { name: databaseName, anyOption: true },
      client: { url: clientUrl, anyOption: 1000 }
    }
  })
)

Some names to replace SomeService:

SimpleDb
EasyDb
DirectlyDb
DirectDb
DbOnly
DbConnection
DbBootstrap
DbResolver
DbInstance
DbClient

With or without suffix Pattern?
If we don't use a suffix, we could use subdirectories like @effect-mongodb/services/<pattern>.ts?
