…ned (#2066)

* optional properties on RedisOptions, SentinelConnectionOptions, ClusterOptions

when exactOptionalPropertyTypes is true in the consuming application's tsconfig, you cannot send in an explicit undefined for these fields, causing the developer to jump through extra hoops needlessly to get i.e. the username and password provided to the options in a type-safe manner. This fix corrects this by explicitly specifying undefined as an allowed type on the username and password properties within RedisOptions, SentinelConnectionOptions, and ClusterOptions.

```ts
new Redis({
  ...
  password: process.env.REDIS_PASSWORD,
})
```

* fix: add missing | undefined to remaining optional properties
