RedisConnector - new connector

[adrianfilip]

#Steps

• Add a new project
  -- Example:

  zio-connect/build.sbt

  Line 38 in 2507925

  lazy val fileConnector = project

• Create the following directory structure

     zio.connect.redis
  

• Create the connector

   sealed trait RedisConnector
   
   case class LiveRedisConnector() extends RedisConnector { ... }
   
   object LiveRedisConnector {
       val layer: ZLayer[???, ???, RedisConnector] = {
           ...
           LiveRedisConnector(...)
       }
  
   }
  

• Provide accessors in the package object
  Example: https://github.com/zio/zio-connect/blob/master/connectors/file-connector/src/main/scala/zio/connect/file/package.scala

• Tests belong in the RedisConnectorSpec file.
  They use the accessors.
  Example:- https://github.com/zio/zio-connect/blob/master/connectors/file-connector/src/test/scala/zio/connect/file/FileConnectorSpec.scala

• There will be a LiveRedisConnectorSpec that runs the RedisConnectorSpec files for the LiveRedisConnector layer
  You can use testcontainers - maybe this one https://github.com/redis-developer/testcontainers-redis
  Example with testcontainers and localstack S3 here - https://github.com/zio/zio-connect/pull/83/files#diff-e7e0899e455a741a644a05c0b26879d176a9126951477cd7c62dc19ade98b5cc

• Provide a TestRedisConnector layer that allows testing with a stub.
  Example - https://github.com/zio/zio-connect/blob/master/connectors/file-connector/src/main/scala/zio/connect/file/TestFileConnector.scala
