Evaluator Server Update

[kiroco12]

Resolved compilation problems caused by the dependencies update. This PR does not solve compilation problems in the test module, this will be added in a future PR.

This evaluator resolves dependencies, compiles and executes code using a REST API. This request code has been used to test the evaluator using postman:

{ "code": "{import cats.effect._\nimport cats.syntax.all._\nimport fetch._\nimport cats.data.NonEmptyList\n\ntrait DataSource[F[_], Identity, Result]{\n def data: Data[Identity, Result]\n\n def CF: Concurrent[F]\n\n def fetch(id: Identity): F[Option[Result]]\n\n def batch(ids: NonEmptyList[Identity]): F[Map[Identity, Result]]\n}\ntype UserId = Int\ncase class User(id: UserId, username: String)\n\ndef latency[F[_] : Concurrent](msg: String): F[Unit] = for {\n _ <- Sync[F].delay(println(s\"--> [${Thread.currentThread.getId}] $msg\"))\n_ <- Sync[F].delay(Thread.sleep(100))\n _ <- Sync[F].delay(println(s\"<-- [${Thread.currentThread.getId}] $msg\"))\n} yield ()}", "resolvers": [ "https://oss.sonatype.org/content/repositories/snapshots", "https://oss.sonatype.org/content/repositories/public" ], "dependencies": [ { "groupId": "com.47deg", "version": "1.2.0", "artifactId": "fetch_2.11" } ] }

Remaining parts to finish the evaluator update are the solution of compilation problems in the server/test module and the creation of a new http client for the client module.
