Unable to use URL in ioredis cache options

[JoeCap08055]

Issue Description

According to the ioredis docs, the following connection options are equivalent within the cache {} block:

cache {
  type: "ioredis",
  options {
     port: 1234,
     host: "myhost",
     db: 1
  }
}

cache {
   type: "ioredis",
   port: 1234,
   options {
      host: "myhost",
      db: 1
   }
}

cache {
   type: "ioredis",
   port: "redis://myhost:1234/1"
}

Expected Behavior

All three config options above produce the same result, which is an ioredis query cache connected to myhost on port 1234, database index 1

Actual Behavior

Option 1 succeeds.
Option 2 ignores port and only uses the values inside the options block, using the ioredis default port 6379. Connection fails.
Option 3 ignores port and attempts to connect to localhost:6379, and fails.

Steps to Reproduce

Try each of the listed cache configs in your ormconfig.js

Does this only work in ioredis?
What about normal redis?
